Flash Builder 4.5的TouchEvents

Question

我已經成功地創建了我的第一個應用程序並將其導入到我的iPhone中，但我似乎無法使TouchEvents正常工作。我究竟做錯了什麼？這裏是我目前的代碼：

package 
{ 
    import flash.display.Graphics; 
    import flash.display.Sprite; 
    import flash.display.StageAlign; 
    import flash.display.StageScaleMode; 
    import flash.events.MouseEvent; 
    import flash.events.TouchEvent; 
    import flash.ui.Multitouch; 
    import flash.ui.MultitouchInputMode; 

    public class TestIos extends Sprite 
    { 
     private var boll:Sprite = new Sprite; 
     private var radius:Number = 40; 

     public function TestIos() 
     { 
      super(); 

      // support autoOrients 
      stage.align = StageAlign.TOP_LEFT; 
      stage.scaleMode = StageScaleMode.NO_SCALE; 

      this.addChild(boll); 

      this.drawBoll(); 

      // Add events 
      boll.addEventListener(TouchEvent.TOUCH_BEGIN,onTouchBegin); 
      boll.addEventListener(TouchEvent.TOUCH_TAP,onTouchTap); 
     } 

     private function onTouchBegin(e:TouchEvent):void { 
      var g:Graphics = boll.graphics; 
      g.clear(); 
      g.beginFill(0xcc66cc,1); 
      g.drawCircle(150,radius,radius); 

      boll.scaleX = boll.scaleY = 1.25; 

      boll.addEventListener(TouchEvent.TOUCH_END,onTouchEnds); 
      boll.addEventListener(TouchEvent.TOUCH_MOVE,onTouchMove); 
     } 

     private function onTouchMove(e:TouchEvent):void { 
      boll.x = e.stageX; 
      boll.y = e.stageY; 
     } 

     private function onTouchTap(e:TouchEvent):void { 
      var g:Graphics = boll.graphics; 
      g.clear(); 
      g.beginFill(0x33cc33,1); 
      g.drawCircle(150,radius,radius); 

      boll.scaleX = boll.scaleY = 1; 
     } 

     private function onTouchEnds(e:TouchEvent):void { 
      this.drawBoll(); 

      boll.removeEventListener(TouchEvent.TOUCH_MOVE,onTouchMove); 
      boll.removeEventListener(TouchEvent.TOUCH_END,onTouchEnds); 
     } 

     private function drawBoll():void { 
      var g:Graphics = boll.graphics; 
      g.clear(); 
      g.beginFill(0x3399cc,1); 
      g.drawCircle(150,radius,radius); 

      boll.scaleX = boll.scaleY = 1; 
     } 
    } 
}

我會推薦你​​look at the API and examples。在這種情況下，您似乎錯過了Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;聲明。
