我的代码加载SWF

var request:URLRequest = new URLRequest("http://xx/loading.swf"); 
       var loader:Loader = new Loader() 
       loader.load(request); 
       addChild(loader); 

Answer 1

  var request:URLRequest = new URLRequest("http://name.swf"); 
      var loader:Loader = new Loader() 
      loader.load(request); 
      uic.addChild(loader); 

      <mx:UIComponent id="uic" width="100%" height="100%"/>
