2.移除

function@H_419_10@ touchableSpriteWithFixedPriority:onExit@H_419_10@()@H_419_10@@H_419_10@    local@H_419_10@ eventdispatcher = self:getEventdispatcher()    eventdispatcher:removeEventListener(self._Listener)end@H_419_10@

3.注意

onEnter和onExit在lua中不会因节点别add和remove而直接被调用，当子节点被父节点add和remove时，会发送enter和exit的消息，所以需要再初始化节点的时候，监听消息，并在收到消息后调用onEnter或onExit。
