InheritanceLoader Inheritance DisplayObjectContainer Inheritance InteractiveObject Inheritance DisplayObject Inheritance EventDispatcher Inheritance Object

Language version: ActionScript 3.0
Runtime version: 

The Loader class is used to load SWF files or image (JPG, PNG, or GIF) files. Use the load() method to initiate loading. The loaded display object is added as a child of the Loader object.

Use the URLLoader class to load text or binary data.

The Loader class overrides the following methods that it inherits, because a Loader object can only have one child display object—the display object that it loads. Calling the following methods throws an exception: addChild(), addChildAt(), removeChild(), removeChildAt(), and setChildIndex(). To remove a loaded display object, you must remove the Loader object from its parent DisplayObjectContainer child array.

iOS notes

In AIR applications on iOS, you can only load a SWF file containing ActionScript from the application package. This restriction includes any ActionScript, such as assets with class names exported for ActionScript. For loading any SWF file, you must load the SWF using the same application domain as the parent SWF, as shown in the following example:

 var loader:Loader = new Loader();
 var url:URLRequest = new URLRequest("swfs/SecondarySwf.swf");
 var loaderContext:LoaderContext = new LoaderContext(false, ApplicationDomain.currentDomain, null);
 loader.load(url, loaderContext);

In addition, on iOS you can't load a SWF file that contains any ActionScript ByteCode (ABC) then unload it and reload it. If you attempt to do this, the runtime throws error 3764.

Prior to AIR 3.6, only SWF files that do not contain ActionScript bytecode can be loaded, regardless of whether they're loaded from the application package or over a network. As an alternative to using an external SWF file with ActionScript, create a SWC library and link it in to your main SWF.

AIR 3.7 and higher supports loading of externally hosted secondary SWFs. The detailed description about this feature can be found here.

These iOS restrictions restrictions do not apply when an application is running in the iOS Simulator (ipa-test-interpreter-simulator or ipa-debug-interpreter-simulator) or interpreter mode (ipa-test-interpreter or ipa-debug-interpreter.)

Loader security

When you use the Loader class, consider the Flash Player and Adobe AIR security model:

However, in AIR, content in the application security sandbox (content installed with the AIR application) are not restricted by these security limitations.

For more information related to security, see the Flash Player Developer Center Topic: Security.

When loading a SWF file from an untrusted source (such as a domain other than that of the Loader object's root SWF file), you may want to define a mask for the Loader object, to prevent the loaded content (which is a child of the Loader object) from drawing to portions of the Stage outside of that mask, as shown in the following code:

 import flash.display.*;
 import flash.net.URLRequest;
 var rect:Shape = new Shape();
 rect.graphics.beginFill(0xFFFFFF);
 rect.graphics.drawRect(0, 0, 100, 100);
 rect.graphics.endFill();
 addChild(rect);
 var ldr:Loader = new Loader();
 ldr.mask = rect;
 var url:String = "http://www.unknown.example.com/content.swf";
 var urlReq:URLRequest = new URLRequest(url);
 ldr.load(urlReq);
 addChild(ldr);
 

Note: App Transport Security is being introduced from Apple in iOS9, which doesn’t allow unsecure connections between App and Web services. Due to this change all the connections which are made to Unsecure web sites via Loader, URLLoader will discontinue and not work due to App Transport Security. Please specify exceptions to the default behaviour by adding keys to Info.plist in your app.

To turn off the feature completely you can add following in your Info.plist and it will work as before.

     <key>NSAppTransportSecurity</key>
               <dict>
                   <key>NSAllowsArbitraryLoads</key><true/>
               </dict>
  

Please specify exceptions to the default behavior by adding keys to InfoAdditions tag of application descriptor of your app.

Property detail
contentproperty
content:DisplayObject  [read-only]

Language version: ActionScript 3.0
Runtime version: 

Contains the root display object of the SWF file or image (JPG, PNG, or GIF) file that was loaded by using the load() or loadBytes() methods.

Implementation
    public function get content():DisplayObject

Throws
SecurityError — The loaded SWF file or image file belongs to a security sandbox to which you do not have access. For a loaded SWF file, you can avoid this situation by having the file call the Security.allowDomain() method or by having the loading file specify a loaderContext parameter with its securityDomain property set to SecurityDomain.currentDomain when you call the load() or loadBytes() method.

See also

contentLoaderInfoproperty 
contentLoaderInfo:LoaderInfo  [read-only]

Language version: ActionScript 3.0
Runtime version: 

Returns a LoaderInfo object corresponding to the object being loaded. LoaderInfo objects are shared between the Loader object and the loaded content object. The LoaderInfo object supplies loading progress information and statistics about the loaded file.

Events related to the load are dispatched by the LoaderInfo object referenced by the contentLoaderInfo property of the Loader object. The contentLoaderInfo property is set to a valid LoaderInfo object, even before the content is loaded, so that you can add event listeners to the object prior to the load.

To detect uncaught errors that happen in a loaded SWF, use the Loader.uncaughtErrorEvents property, not the Loader.contentLoaderInfo.uncaughtErrorEvents property.

Implementation
    public function get contentLoaderInfo():LoaderInfo

See also


Example
The following example shows how you can load and position an image in ActionScript 3.0 using the Loader class and the complete event on the Loader object's contentLoaderInfo property. Example provided by ActionScriptExamples.com.
var url:String = "http://www.helpexamples.com/flash/images/image2.jpg";
var urlRequest:URLRequest = new URLRequest(url);
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loader_complete);
loader.load(urlRequest);
addChild(loader);
 
function loader_complete(evt:Event):void {
    var target_mc:Loader = evt.currentTarget.loader as Loader;
    target_mc.x = (stage.stageWidth - target_mc.width) / 2;
    target_mc.y = (stage.stageHeight - target_mc.height) / 2;
}

uncaughtErrorEventsproperty 
uncaughtErrorEvents:UncaughtErrorEvents  [read-only]

Language version: ActionScript 3.0
Runtime version: AIR 2

An object that dispatches an uncaughtError event when an unhandled error occurs in the SWF that's loaded by this Loader object. An uncaught error happens when an error is thrown outside of any try..catch blocks or when an ErrorEvent object is dispatched with no registered listeners.

Note that a Loader object's uncaughtErrorEvents property dispatches events that bubble through it, not events that it dispatches directly. It never dispatches an uncaughtErrorEvent in the target phase. It only dispatches the event in the capture and bubbling phases. To detect an uncaught error in the current SWF (the SWF in which the Loader object is defined) use the LoaderInfo.uncaughtErrorEvents property instead.

If the content loaded by the Loader object is an AVM1 (ActionScript 2) SWF file, uncaught errors in the AVM1 SWF file do not result in an uncaughtError event.

Implementation
    public function get uncaughtErrorEvents():UncaughtErrorEvents

Example
The following example demonstrates the use of an uncaught error event handler to detect uncaught errors in a loaded SWF. The example defines an uncaughtError event handler to detect uncaught errors.

In the constructor, the code creates a Loader object and registers a listener for the uncaughtError event dispatched by the Loader object's uncaughtErrorEvents property.

In the uncaughtErrorHandler() method, the code checks the data type of the error property and responds accordingly.

package
{
    import flash.display.Loader;
    import flash.display.Sprite;
	import flash.events.ErrorEvent;
	import flash.events.UncaughtErrorEvent;
	import flash.net.URLRequest;

    public class LoaderUncaughtErrorEventExample extends Sprite
    {
		private var ldr:Loader;
		
        public function LoaderUncaughtErrorEventExample()
        {
			ldr = new Loader();
			ldr.load(new URLRequest("child.swf"));
            ldr.uncaughtErrorEvents.addEventListener(UncaughtErrorEvent.UNCAUGHT_ERROR, uncaughtErrorHandler);
        }
		
        private function uncaughtErrorHandler(event:UncaughtErrorEvent):void
        {
            if (event.error is Error)
            {
                var error:Error = event.error as Error;
				// do something with the error
            }
            else if (event.error is ErrorEvent)
            {
                var errorEvent:ErrorEvent = event.error as ErrorEvent;
				// do something with the error
            }
            else
            {
                // a non-Error, non-ErrorEvent type was thrown and uncaught
            }
        }
    }
}

Constructor detail
Loader()constructor
public function Loader()

Language version: ActionScript 3.0
Runtime version: 

Creates a Loader object that you can use to load files, such as SWF, JPEG, GIF, or PNG files. Call the load() method to load the asset as a child of the Loader instance. You can then add the Loader object to the display list (for instance, by using the addChild() method of a DisplayObjectContainer instance). The asset appears on the Stage as it loads.

You can also use a Loader instance "offlist," that is without adding it to a display object container on the display list. In this mode, the Loader instance might be used to load a SWF file that contains additional modules of an application.

To detect when the SWF file is finished loading, you can use the events of the LoaderInfo object associated with the contentLoaderInfo property of the Loader object. At that point, the code in the module SWF file can be executed to initialize and start the module. In the offlist mode, a Loader instance might also be used to load a SWF file that contains components or media assets. Again, you can use the LoaderInfo object event notifications to detect when the components are finished loading. At that point, the application can start using the components and media assets in the library of the SWF file by instantiating the ActionScript 3.0 classes that represent those components and assets.

To determine the status of a Loader object, monitor the following events that the LoaderInfo object associated with the contentLoaderInfo property of the Loader object:

Notes (iOS only): In AIR applications on iOS, you can only load a SWF file containing ActionScript from the application package. This restriction includes any ActionScript, such as assets with class names exported for ActionScript. For loading any SWF file, you must load the SWF using the same application domain as the parent SWF.

Prior to AIR 3.6, only SWF files that do not contain ActionScript bytecode can be loaded, regardless of whether they're loaded from the application package or over a network. As an alternative to using an external SWF file with ActionScript, create a SWC library and link it in to your main SWF.

These restrictions do not apply when an application is running in the iOS Simulator (ipa-test-interpreter-simulator or ipa-debug-interpreter-simulator) or interpreter mode (ipa-test-interpreter or ipa-debug-interpreter.)

Method detail
close()method
public function close():void

Language version: ActionScript 3.0
Runtime version: 

Cancels a load() method operation that is currently in progress for the Loader instance.

See also

load()method 
public function load(request:URLRequest, context:LoaderContext = null):void

Language version: ActionScript 3.0
Runtime version: 

Loads a SWF, JPEG, progressive JPEG, unanimated GIF, or PNG file into an object that is a child of this Loader object. If you load an animated GIF file, only the first frame is displayed. As the Loader object can contain only a single child, issuing a subsequent load() request terminates the previous request, if still pending, and commences a new load.

Note: In AIR 1.5 and Flash Player 10, the maximum size for a loaded image is 8,191 pixels in width or height, and the total number of pixels cannot exceed 16,777,215 pixels. (So, if an loaded image is 8,191 pixels wide, it can only be 2,048 pixels high.) In Flash Player 9 and earlier and AIR 1.1 and earlier, the limitation is 2,880 pixels in height and 2,880 pixels in width.

A SWF file or image loaded into a Loader object inherits the position, rotation, and scale properties of the parent display objects of the Loader object.

Use the unload() method to remove movies or images loaded with this method, or to cancel a load operation that is in progress.

You can prevent a SWF file from using this method by setting the allowNetworking parameter of the the object and embed tags in the HTML page that contains the SWF content.

iOS notes

In AIR applications on iOS, you can only load a SWF file containing ActionScript from the application package. This restriction includes any ActionScript, such as assets with class names exported for ActionScript. For loading any SWF file, you must load the SWF using the same application domain as the parent SWF, as shown in the following example:

     var loader:Loader = new Loader();
     var url:URLRequest = new URLRequest("swfs/SecondarySwf.swf");
     var loaderContext:LoaderContext = new LoaderContext(false, ApplicationDomain.currentDomain, null);
     loader.load(url, loaderContext);

In addition, on iOS you can't load a SWF file that contains any ActionScript ByteCode (ABC) then unload it and reload it. If you attempt to do this, the runtime throws error 3764.

Prior to AIR 3.6, only SWF files that do not contain ActionScript bytecode can be loaded, regardless of whether they're loaded from the application package or over a network. As an alternative to using an external SWF file with ActionScript, create a SWC library and link it in to your main SWF.

These restrictions do not apply when an application is running in the iOS Simulator (ipa-test-interpreter-simulator or ipa-debug-interpreter-simulator) or interpreter mode (ipa-test-interpreter or ipa-debug-interpreter.)

Loader security

When you use this method, consider the Flash Player security model, which is described in the Loader class description.

In Flash Player 10 and later, if you use a multipart Content-Type (for example "multipart/form-data") that contains an upload (indicated by a "filename" parameter in a "content-disposition" header within the POST body), the POST operation is subject to the security rules applied to uploads:

Also, for any multipart Content-Type, the syntax must be valid (according to the RFC2046 standard). If the syntax appears to be invalid, the POST operation is subject to the security rules applied to uploads.

For more information related to security, see the Flash Player Developer Center Topic: Security.

Parameters
request:URLRequest — The absolute or relative URL of the SWF, JPEG, GIF, or PNG file to be loaded. A relative path must be relative to the main SWF file. Absolute URLs must include the protocol reference, such as http:// or file:///. Filenames cannot include disk drive specifications.
 
context:LoaderContext (default = null) — A LoaderContext object, which has properties that define the following:
  • Whether or not to check for the existence of a policy file upon loading the object
  • The ApplicationDomain for the loaded object
  • The SecurityDomain for the loaded object
  • The ImageDecodingPolicy for the loaded image object

If the context parameter is not specified or refers to a null object, the loaded content remains in its own security domain.

iOS only: When calling the load() method in AIR for iOS, the LoaderContext instance must specify the main application domain (ApplicationDomain.currentDomain).

For complete details, see the description of the properties in the LoaderContext class.


Events
asyncError:AsyncErrorEvent — Dispatched by the contentLoaderInfo object if the LoaderContext.requestedContentParent property has been specified and it is not possible to add the loaded content as a child to the specified DisplayObjectContainer. This could happen if the loaded content is a flash.display.AVM1Movie or if the addChild() call to the requestedContentParent throws an error.
 
complete:Event — Dispatched by the contentLoaderInfo object when the file has completed loading. The complete event is always dispatched after the init event.
 
httpStatus:HTTPStatusEvent — Dispatched by the contentLoaderInfo object when a network request is made over HTTP and Flash Player can detect the HTTP status code.
 
init:Event — Dispatched by the contentLoaderInfo object when the properties and methods of the loaded SWF file are accessible. The init event always precedes the complete event.
 
ioError:IOErrorEvent — Dispatched by the contentLoaderInfo object when an input or output error occurs that causes a load operation to fail.
 
open:Event — Dispatched by the contentLoaderInfo object when the loading operation starts.
 
progress:ProgressEvent — Dispatched by the contentLoaderInfo object as data is received while load operation progresses.
 
securityError:SecurityErrorEvent — Dispatched by the contentLoaderInfo object if a SWF file in the local-with-filesystem sandbox attempts to load content in the local-with-networking sandbox, or vice versa.
 
securityError:SecurityErrorEvent — Dispatched by the contentLoaderInfo object if the LoaderContext.requestedContentParent property has been specified and the security sandbox of the LoaderContext.requestedContentParent does not have access to the loaded SWF.
 
unload:Event — Dispatched by the contentLoaderInfo object when a loaded object is removed.

Throws
Error — The digest property of the request object is not null. You should only set the digest property of a URLRequest object when calling the URLLoader.load() method when loading a SWZ file (an Adobe platform component).
 
SecurityError — The value of LoaderContext.securityDomain must be either null or SecurityDomain.currentDomain. This reflects the fact that you can only place the loaded media in its natural security sandbox or your own (the latter requires a policy file).
 
SecurityError — Local SWF files may not set LoaderContext.securityDomain to anything other than null. It is not permitted to import non-local media into a local sandbox, or to place other local media in anything other than its natural sandbox.
 
SecurityError — You cannot connect to commonly reserved ports. For a complete list of blocked ports, see "Restricting Networking APIs" in the ActionScript 3.0 Developer's Guide.
 
SecurityError — If the applicationDomain or securityDomain properties of the context parameter are from a disallowed domain.
 
SecurityError — If a local SWF file is attempting to use the securityDomain property of the context parameter.
 
Error — If the requestedContentParent property of the context parameter is a Loader.
 
Error — If the LoaderContext.parameters parameter is set to non-null and has some values which are not Strings.
 
Error — On iOS, if the application attempts to load a SWF file in an application domain other than the main application domain.
 
Error — On iOS, if the application attempts to reload a SWF that has been loaded and unloaded and the SWF contains ABC code.
 
Error — On iOS, if the application attempts to load a SWF file from outside the application package that contains ActionScript code. This error can't be caught. It appears as a dialog box on the app screen with the title "Uncompiled ActionScript." Prior to AIR 3.6, this error occurs when you attempt to load any SWF file containing ActionScript, whether it is external or included in the application package.

loadBytes()method 
public function loadBytes(bytes:ByteArray, context:LoaderContext = null):void

Language version: ActionScript 3.0
Runtime version: 

Loads from binary data stored in a ByteArray object.

The loadBytes() method is asynchronous. You must wait for the "init" event before accessing the properties of a loaded object.

When you use this method, consider the Flash Player security model, which is described in the Loader class description.

Note (iOS only): In AIR applications on iOS, you can only load a SWF file containing ActionScript from the application package. This restriction includes any ActionScript, such as assets with class names exported for ActionScript. For loading any SWF file, you must load the SWF using the same application domain as the parent SWF.

Prior to AIR 3.6, calling this method has no effect on iOS.

Parameters
bytes:ByteArray — A ByteArray object. The contents of the ByteArray can be any of the file formats supported by the Loader class: SWF, GIF, JPEG, or PNG.
 
context:LoaderContext (default = null) — A LoaderContext object. Only the applicationDomain property of the LoaderContext object applies; the checkPolicyFile and securityDomain properties of the LoaderContext object do not apply.

If the context parameter is not specified or refers to a null object, the content is loaded into the current security domain— a process referred to as "import loading" in Flash Player security documentation. Specifically, if the loading SWF file trusts the remote SWF by incorporating the remote SWF into its code, then the loading SWF can import it directly into its own security domain.

For more information related to security, see the Flash Player Developer Center Topic: Security.


Events
asyncError:AsyncErrorEvent — Dispatched by the contentLoaderInfo object if the LoaderContext.requestedContentParent property has been specified and it is not possible to add the loaded content as a child to the specified DisplayObjectContainer. This could happen if the loaded content is a flash.display.AVM1Movie or if the addChild() call to the requestedContentParent throws an error.
 
complete:Event — Dispatched by the contentLoaderInfo object when the operation is complete. The complete event is always dispatched after the init event.
 
init:Event — Dispatched by the contentLoaderInfo object when the properties and methods of the loaded data are accessible. The init event always precedes the complete event.
 
ioError:IOErrorEvent — Dispatched by the contentLoaderInfo object when the runtime cannot parse the data in the byte array.
 
open:Event — Dispatched by the contentLoaderInfo object when the operation starts.
 
progress:ProgressEvent — Dispatched by the contentLoaderInfo object as data is transfered in memory.
 
securityError:SecurityErrorEvent — Dispatched by the contentLoaderInfo object if the LoaderContext.requestedContentParent property has been specified and the security sandbox of the LoaderContext.requestedContentParent does not have access to the loaded SWF.
 
unload:Event — Dispatched by the contentLoaderInfo object when a loaded object is removed.

Throws
ArgumentError — If the length property of the ByteArray object is not greater than 0.
 
Error — If the checkPolicyFile or securityDomain property of the context parameter are non-null.
 
Error — If the requestedContentParent property of the context parameter is a Loader.
 
Error — If the LoaderContext.parameters parameter is set to non-null and has some values which are not Strings.
 
Error — On iOS, if the application attempts to load a SWF file in an application domain other than the main application domain.
 
Error — On iOS, if the application attempts to reload a SWF that has been loaded and unloaded and that contains ABC code.
 
Error — On iOS, if the application attempts to load a SWF file from outside the application package that contains ActionScript code. This error can't be caught. It appears as a dialog box on the app screen with the message "Uncompiled ActionScript." Prior to AIR 3.6, this error occurs when you attempt to load any SWF file containing ActionScript, whether it is external or included in the application package.
 
SecurityError — If the provided applicationDomain property of the context property is from a disallowed domain.
 
SecurityError — You cannot connect to commonly reserved ports. For a complete list of blocked ports, see "Restricting Networking APIs" in the ActionScript 3.0 Developer's Guide.

loadFilePromise()method 
public function loadFilePromise(promise:IFilePromise, context:LoaderContext = null):void

Language version: ActionScript 3.0
Runtime version: AIR 2.5

Loads an IFilePromise instance.

The loadFilePromise method takes an IFilePromise object and loads the binary data. If the data is a progressive stream, such as a video wait for the "init" or progress events before accessing the properties of the loaded object. Otherwise, wait for the complete event to make sure that the data is fully loaded.

When you use this method, consider the Flash Player security model, which is described in the Loader class description.

Parameters
promise:IFilePromise — An IFilePromise object. The data source of the object can be any of the file formats supported by the Loader class: SWF, GIF, JPEG, or PNG.
 
context:LoaderContext (default = null) — A LoaderContext object. Only the applicationDomain property of the LoaderContext object applies; the checkPolicyFile and securityDomain properties of the LoaderContext object do not apply.

If the context parameter is not specified or refers to a null object, the content is loaded into the current security domain— a process referred to as "import loading" in Flash Player security documentation. Specifically, if the loading SWF file trusts the remote SWF by incorporating the remote SWF into its code, then the loading SWF can import it directly into its own security domain.

For more information related to security, see the Flash Player Developer Center Topic: Security.


Events
asyncError:AsyncErrorEvent — Dispatched by the contentLoaderInfo object if the LoaderContext.requestedContentParent property has been specified and it is not possible to add the loaded content as a child to the specified DisplayObjectContainer. This could happen if the loaded content is a flash.display.AVM1Movie or if the addChild() call to the requestedContentParent throws an error.
 
complete:Event — Dispatched by the contentLoaderInfo object when the operation is complete. The complete event is always dispatched after the init event.
 
init:Event — Dispatched by the contentLoaderInfo object when the properties and methods of the loaded data are accessible. The init event always precedes the complete event.
 
ioError:IOErrorEvent — Dispatched by the contentLoaderInfo object when the runtime cannot parse the data in the data source or if the data source stream is not readable.
 
open:Event — Dispatched by the contentLoaderInfo object when the operation starts.
 
progress:ProgressEvent — Dispatched by the contentLoaderInfo object as data is transfered in memory.
 
securityError:SecurityErrorEvent — Dispatched by the contentLoaderInfo object if the LoaderContext.requestedContentParent property has been specified and the security sandbox of the LoaderContext.requestedContentParent does not have access to the loaded SWF.
 
unload:Event — Dispatched by the contentLoaderInfo object when a loaded object is removed.

Throws
Error — If the requestedContentParent property of the context parameter is a Loader.
 
Error — If the LoaderContext.parameters parameter is set to non-null and has some values which are not Strings.
 
ArgumentError — If the IFilePromise object passed as parameter is null

unload()method 
public function unload():void

Language version: ActionScript 3.0
Runtime version: 

Removes a child of this Loader object that was loaded by using the load() method. The property of the associated LoaderInfo object is reset to null. The child is not necessarily destroyed because other objects might have references to it; however, it is no longer a child of the Loader object.

When you call the unload() method, the Loader object's contentLoaderInfo property is set to null. Any visual assets that were loaded with the SWF are unloaded and removed from memory. ActionScript class definitions in the loaded SWF remain in memory, and code in the same application domain as the loaded SWF can access instances of those classes and create new instances.

Note (iOS only): Prior to AIR 3.6, this method has no effect on iOS.

As a best practice, before you unload a child SWF file, you should explicitly close any streams in the child SWF file's objects, such as LocalConnection, NetConnection, NetStream, and Sound objects. Otherwise, audio in the child SWF file might continue to play, even though the child SWF file was unloaded. To close streams in the child SWF file, add an event listener to the child that listens for the unload event. When the parent calls Loader.unload(), the unload event is dispatched to the child. The following code shows how you might do this:

function closeAllStreams(evt:Event) { 
    myNetStream.close();
    mySound.close();
    myNetConnection.close();
    myLocalConnection.close();
}

myMovieClip.loaderInfo.addEventListener(Event.UNLOAD, closeAllStreams);

unloadAndStop()method 
public function unloadAndStop(gc:Boolean = true):void

Language version: ActionScript 3.0
Runtime version: AIR 1.5

Attempts to unload child SWF file contents and stops the execution of commands from loaded SWF files. This method attempts to unload SWF files that were loaded using Loader.load() or Loader.loadBytes() by removing references to EventDispatcher, NetConnection, Timer, Sound, or Video objects of the child SWF file. As a result, the following occurs for the child SWF file and the child SWF file's display list:

When you call the unloadAndStop() method, the Loader object's contentLoaderInfo property is set to null. Any visual assets that were loaded with the SWF are unloaded and removed from memory. ActionScript class definitions in the loaded SWF remain in memory, and code in the same application domain as the loaded SWF can access instances of those classes and create new instances.

Note (iOS only): Prior to AIR 3.6, this method has no effect on iOS.

Parameters
gc:Boolean (default = true) — Provides a hint to the garbage collector to run on the child SWF objects (true) or not (false). If you are unloading many objects asynchronously, setting the gc paramter to false might improve application performance. However, if the parameter is set to false, media and display objects of the child SWF file might persist in memory after running the unloadAndStop() command.

Examples
examples\LoaderExample
The following example uses the LoaderExample class to illustrate how various event listeners are used. This task is accomplished by performing the following steps:
  1. A url property is created, which is the location and name of the image file
  2. In the LoaderExample constructor, a new Loader object named loader is created, which is then passed to the configureListeners() method, described in step 3.
  3. The constructor creates a new instance of a URLRequest object, request, with url passed so that the file name and location are known.
  4. The request object is passed to the loader object's load() method, which loads the image onto the display list.
  5. A clickHandler event listener is registered for the click event on the loader. After a mouse click, the loaded image is unloaded.
  6. The configureListeners() method adds seven event listeners by using the following methods:
    • The completeHandler() method executes when the image finishes loading.
    • The httpStatusHandler() method executes if the image is not loaded locally and only if the network request is made available and the Flash Player can detect it.
    • The initHandler() method executes before the completeHandler() method and after the progressHandler() method. Generally, the init event is more useful when loading SWF files.
    • The ioErrorHandler() method executes if the image file is not available or not accessible.
    • The openHandler() method executes when the image file is first opened.
    • The progressHandler() method executes when the image file starts to load and again when the image is finished loading.
    • The unLoadHandler() method executes when the image is unloaded by using the unload() method when the user clicks the image.
