绑定 eventListener 问题

Question

我对我的事件与你们各自的 sprite 的绑定有疑问。

这是我的代码：

var GameLayer = cc.Layer.extend({
    sprite:null,
    ctor:function () {
        this._super();
        var size = cc.winSize;

        var gradient = cc.LayerGradient(cc.color(0,0,0,255),cc.color(0x46,0x82,0xB4,255));
        this.addChild(gradient);

        for(i=0;i<16;i++){
            var tile = new MemoryTile();
            this.addChild(tile,0);
            tile.setPosition(49+i%4*74,400-Math.floor(i/4)*74);
        }

        return true;
    }
});


var MemoryTile = cc.Sprite.extend({
    ctor:function() {
        this._super();
        this.initWithFile(res.cover);

        var listener = cc.EventListener.create({
        event: cc.EventListener.TOUCH_ONE_BY_ONE,
        swallowTouches: true,
        onTouchBegan: function (touch, event) {
            var target = event.getCurrentTarget();
            var location = target.convertToNodeSpace(touch.getLocation());
            var targetSize = target.getContentSize();
            var targetRectangle = cc.rect(0, 0, targetSize.width, targetSize.height);
                if (cc.rectContainsPoint(targetRectangle, location)) {
                    console.log("I picked a tile!!");
                }
                //console.log('touche po oe: ' + targetSize);    
                return true;
            }
        });

        cc.eventManager.addListener(listener.clone(), this);
    }
});

所以，问题是只有第一个 sprite 仍然使用 eventListener 创建，我认为 listener.clone() 不起作用，我的任何想法做错了吗？

我认为 create 方法已被弃用，这应该可以在内存块而不是 var 侦听器和 add 侦听器中正常工作：

cc.eventManager.addListener({
            event: cc.EventListener.TOUCH_ONE_BY_ONE,
            swallowTouches: false,
            onTouchBegan: function (touch, event) {
                var target = event.getCurrentTarget();
                var location = target.convertToNodeSpace(touch.getLocation());
                var targetSize = target.getContentSize();
                var targetRectangle = cc.rect(0, 0, targetSize.width, targetSize.height);
                if (cc.rectContainsPoint(targetRectangle, location)) {
                    console.log("I picked a tile!!");
                }
                //console.log('touche po oe: ' + targetSize);   
                return true;
            }
        }, this);
