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高于按钮-128的层级

auto touchListener=EventListenerTouchOneByOne::create();
	touchListener->onTouchBegan=[=](Touch *touch,Event *event)
	{
		touchListener->setSwallowTouches(true);
		return true;
	};
	_eventDispatcher->addEventListenerWithFixedPriority(touchListener,-139);
