cocos2d-x，点击出现弹出窗口，如何将下面层的点击事件禁掉？需要设置listener:setSwallowTouches(true)，这样就不会触发下一层的事件，还有在onTouchBegan中返回true

如

	local layerColor=Layer2.new()
	
	 local function onTouchBegan(touch,event)
	 return true
	 end
	
	
    local listener=cc.EventListenerTouchOneByOne:create()
    listener:setSwallowTouches(true)
    listener:registerScriptHandler(onTouchBegan,cc.Handler.EVENT_TOUCH_BEGAN)
    local eventDispatcher = layerColor:getEventDispatcher()
    eventDispatcher:addEventListenerWithSceneGraPHPriority(listener,layerColor)
