getDefinitionByName with swc

一般 Flash 程式開發時, 取資源的方式有兩種:

• .swf
• .swc

.swf 擋屬於 Runtime 時從外部載進來取用的方式, 通常會使用 Loader 來作處理.

	var loader:Loader = new Loader();
	var request:URLRequest = new URLRequest('YOUR_SWF_PATH');
	loader = new Loader();
	loader.load(request);
	loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoaderComplete);
	private function onLoaderComplete(event:Event):void
	{
	var loader:LoaderInfo = event.currentTarget as LoaderInfo;
	loader.removeEventListener(Event.COMPLETE, onLoaderComplete);
	}
	private function getClassReference(className:String):Class
	{
	return loader.contentLoaderInfo.getDefinition(className) as Class;
	}

.swc 擋則是 Compiler 時就會一起包進來, 要取用內部元件通常就直接 new 出來就可以:
var component:CLASS_NAME = new CLASS_NAME();
如果想要動態取得元件的話會碰到一些問題, 一般來講會用 getDefinitionByName(CLASS_NAME:String) 這個 method:

	import flash.utils.getDefinitionByName;
	var ClassReference:Class = getDefinitionByName("CLASS_NAME") as Class;
	var obj:Object = new ClassReference();

不過編譯完執行後會碰到錯誤, 解決方式如下:
Project > Properties

Flex Compiler > 加入下面參數
-include-libraries=YOUR_ABSOLUTE_SWC_PATH.swc
