ios - 如何在适用于 iOS 的 Adob​​e AIR 中同时收听点击和手势？

Question

我正在制作一款 iOS 游戏，我需要同时检测简单的点击和手势(滑动等)。在 AIR 中，我只能看到一个用于多点触控输入模式的设置:TOUCH_POINT(适用于基本点击)和 GESTURE。但我同时需要两者，所以改变模式不是一种选择。如何同时收听两者？

谢谢，可以。

import flash.events.EventDispatcher;
import flash.events.TouchEvent;
import flash.net.Responder;
import flash.ui.Multitouch;
import flash.ui.MultitouchInputMode;

public class SwipeAndTap extends EventDispatcher
{
    private var fingerX:int;
    private var fingerY:int;
    private var elem:Object;

    public function SwipeAndTap(_elem:Object)
    {
        Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;

        elem = _elem;
        elem.addEventListener(TouchEvent.TOUCH_BEGIN, onTouchBegin);
        elem.addEventListener(TouchEvent.TOUCH_MOVE, onTouchMove);
        elem.addEventListener(TouchEvent.TOUCH_END, onTouchEnd);
    }
    private function onTouchBegin(e:TouchEvent):void 
    {
        fingerX = e.stageX;
        fingerY = e.stageY;
    }
    private function onTouchMove(e:TouchEvent):void 
    {
        if(e.stageX > (fingerX+150) && (e.stageY > (fingerY-100) && e.stageY < (fingerY+100) ) )
        {
            // swipe right
            dispatchEvent(new TouchSwipeRight(TouchSwipeRight.SWIPE_RIGHT, e));
        }
        else if(e.stageX < (fingerX-150) && (e.stageY > (fingerY-100) && e.stageY < (fingerY+100) ) )
        {
            // swipe left
            dispatchEvent(new TouchSwipeLeft(TouchSwipeLeft.SWIPE_LEFT, e));
        }
    }

    private function onTouchEnd(e:TouchEvent):void 
    { 
        // e.touchPointID;
        if(e.stageX > (fingerX-40) && e.stageX < (fingerX+40))
        {
            dispatchEvent(new TouchEventTap(TouchEventTap.TAP, e));
            elem.removeEventListener(TouchEvent.TOUCH_BEGIN, onTouchBegin);
            elem.removeEventListener(TouchEvent.TOUCH_MOVE, onTouchMove);
            elem.removeEventListener(TouchEvent.TOUCH_END, onTouchEnd);
        }

    }
}

例子:

var SAT:SwipeAndTap = new SwipeAndTap(stage);
    SAT.addEventListener(TouchEventTap.TAP, LangSelected);
    SAT.addEventListener(TouchSwipeRight.SWIPE_RIGHT, ENtoPL);
    SAT.addEventListener(TouchSwipeLeft.SWIPE_LEFT, PLtoEN);
