iOS上的Starling – Touch事件处理程序“死亡”

我有一个方法，在Box2d中施加一个球的力量。

在桌面上本地testing它可以正常工作，但在iPad（ios7）上，该方法只能执行到一半！

我从来没有过这么奇怪的错误，这里有什么错误：

function onTouch(e:TouchEvent) { var touch:Touch = e.getTouch(this) as Touch; if (touch && touch.phase == TouchPhase.ENDED) { //do something _debugT.text = "works"; var mouseX_m:Number = touch.globalX; var mouseY_m:Number = touch.globalY; _debugT.text = "stops here..."; var xDiff:Number = mouseX_m - (_whiteBall.GetPosition().x * WORLD_SCALE); var yDiff:Number = mouseY_m - (_whiteBall.GetPosition().y * WORLD_SCALE); var angle:Number = Math.atan2(yDiff, xDiff); var angleDeg:Number = angle * 180 / Math.PI; _debugT.text = "never gets executed" var len = Math.sqrt((xDiff * xDiff) + (yDiff * yDiff)); var vx = len * Math.cos(angle); var vy = len * Math.sin(angle); var vel = _whiteBall.GetLinearVelocity(); vel.x += (vx * 5); vel.y += (vy * 5); var force = new b2Vec2(vel.x, vel.y); _whiteBall.SetAwake(vel); _whiteBall.SetLinearVelocity(force); } }

对我来说，它看起来像Multitouch.inputMode = MultitouchInputMode.GESTURE; 导致这个问题。

我有同样的问题，并注释掉这一行，现在它的作品。
