?flex 加载方式3：通过actionScript加载，通过loader加载字体然后调用getDefinitionByName()获得字体Class，注册字体后，就可以用了。

			fontLoader.contentLoaderInfo.removeEventListener(Event.COMPLETE,loadFontCompleteHandler);
			var alphaFitnessFontClazz:Class = getDefinitionByName("AlphaFitnessFont") as Class;
			
			Font.registerFont(alphaFitnessFontClazz);
			var alphaFitnessFont:Font = new alphaFitnessFontClazz() as Font;
			
			var textFormat:TextFormat = new TextFormat(alphaFitnessFont.fontName,60,null,true);

			textField.embedFonts = true;
			textField.text = "Hello,zhz!!!";
		}

打包ttf为swf字体代码：

package
{
	import flash.display.Sprite;
	
	public class FontAssets extends Sprite
	{
		 [Embed(source="font/AlphaFitness.ttf",fontName="zhzFont1",mimeType="application/x-font")]
		 public var pixelFont1:Class;
		 
		 [Embed(source="font/WeibeiFont.ttf",fontName="zhzFont2",mimeType="application/x-font")]
		 public var pixelFont2:Class;
		 
		 [Embed(source="font/WindTailsFont.ttf",fontName="zhzFont3",mimeType="application/x-font")]
		 public var pixelFont3:Class;
		 
		 [Embed(source="font/YayaSimplifiedFont.ttf",fontName="zhzFont4",mimeType="application/x-font")]
		 public var pixelFont4:Class;
		 
		 [Embed(source="font/YegenyouSimplifiedFont.ttf",fontName="zhzFont5",mimeType="application/x-font")]
		 public var pixelFont5:Class;
	}
}
