scrollview添加的多点触摸没反应

Cocos2d-x JavaScript
#1 
 this.sprite = cc.Sprite.create(res.HelloWorld_png);
        this.sprite.x=this.sprite.width/2;
        this.sprite.y=this.sprite.height/2; 
        var shopscrollview = ccui.ScrollView.create();
        shopscrollview.setDirection(ccui.ScrollView.DIR_BOTH);
        shopscrollview.setTouchEnabled(true);
        shopscrollview.setSize(cc.size(this.sprite.width, this.sprite.height));
        shopscrollview.setBounceEnabled(true); 

        var scrollViewRect = shopscrollview.getSize();
        shopscrollview.x = 0;
        shopscrollview.y = 0;  
        shopscrollview.setInnerContainerSize(cc.size(scrollViewRect.width, scrollViewRect.height));
        shopscrollview.addChild(this.sprite);
        this.addChild(shopscrollview);
        
        cc.eventManager.addListener({
            event: cc.EventListener.TOUCH_ALL_AT_ONCE,
            swallowTouches: true,
            onTouchesBegan: function (touches, event) {
                    
            },
            onTouchesMoved: function (touches, event) {
                var len = touches.length;
                cc.log(len);
            },
            onTouchesEnded: function (touches, event) {
                
            }
        }, shopscrollview);


```
