cocos2d-x3.x屏蔽触摸遮罩层屏蔽按钮

cocos2d-x3.x之后触摸方法有所改变，要屏蔽掉某一层的触摸事件其实很简单，首先touchbegan一定要返回true，其次给监听事件设置吞噬触摸为true，最后注册触摸层级一定要小于0，目前不能设置层级为0了，切记

<span style="font-size:18px;">auto touchListener=EventListenerTouchOneByOne::create();
	touchListener->onTouchBegan=[=](Touch *touch,Event *event)
	{
		touchListener->setSwallowTouches(true);
		return true;
	};
	_eventDispatcher->addEventListenerWithFixedPriority(touchListener,-5); //也可以把-5换成this</span>

或者这么写，其实都是一个道理

<span style="font-size:18px;">	auto callBack = [](Touch*, Event*)
	{
		return true;
	};
	EventListenerTouchOneByOne* listener = EventListenerTouchOneByOne::create();
	listener->onTouchBegan = callBack;
	listener->setSwallowTouches(true);
	_eventDispatcher->addEventListenerWithSceneGraphPriority(listener,this);</span>
