cocos2d-x 3.10 按钮监听时bug的解决--

对触摸按钮事件有四种状态,忘记取消在按钮上滑动的状态,导致一个bug

 local function myCallback(sender,eventType)
            print(sender:getTag())
            if eventType == ccui.TouchEventType.began then
                     print("this is touch began......)
            elseif eventType == ccui.TouchEventType.ended then
                 print("this is touch ended......)
            elseif eventType == ccui.TouchEventType.moved then
                print("this is touch Moved ......)
            elseif eventType == ccui.TouchEventType.canceled then
                print("this is touch Moved canceled ......)
            end

   end 

 local btn = rootNode:getChildByName("Rbt")

                 :addTouchEventListener(myCallback)
