AS3 StageOrientationEvent.ORIENTATION_CHANGING无法在iPad3 iOS6上运行

Question

任何想法为什么我的代码不能在iPad 3 iOS 6上运行，或者它是Adobe air的错误？

以下代码适用于iPad和iPad 2及iOS5

            if (startOrientation == StageOrientation.DEFAULT || startOrientation == StageOrientation.UPSIDE_DOWN){
                stage.setOrientation(StageOrientation.ROTATED_RIGHT);}
            else{
                stage.setOrientation(startOrientation);
            }           

            stage.addEventListener(StageOrientationEvent.ORIENTATION_CHANGING, orientationChangeListener);

private function orientationChangeListener(e:StageOrientationEvent):void{
            txt_rotate.text = 'Camed' + StageOrientation.ROTATED_LEFT;
           if (e.afterOrientation == StageOrientation.DEFAULT || e.afterOrientation ==  StageOrientation.UPSIDE_DOWN){
                e.preventDefault();
           }else if(e.afterOrientation ==  StageOrientation.ROTATED_LEFT){
               _stageOrientation = 'ROTATED_LEFT';
               txt_rotate.text = _stageOrientation;
           }else if(e.afterOrientation ==  StageOrientation.ROTATED_RIGHT){
               _stageOrientation = 'ROTATED_RIGHT';
               txt_rotate.text = _stageOrientation;
           }
        }

Apple在iOS6 SDK中对方向回调进行了一些修改，因此不推荐使用某些功能。

preventDefault函数不能在StageOrientationEvent上运行。建议在需要时将Stage.autoOrients用于false。
