auto listener=EventListenerTouchOneByOne::create();
listener->setSwallowTouches(true);
listener->onTouchBegan=CC_CALLBACK_2(HelloWorld::onTouchBegan,this);
listener->onTouchMoved=CC_CALLBACK_2(HelloWorld::onTouchMoved,this);
listener->onTouchEnded=CC_CALLBACK_2(HelloWorld::onTouchEnded,this);
_eventDispatcher->addEventListenerWithSceneGraphPriority(listener,bg );//只给bg注册
如上，只给bg注册了监听事件，但是运行后s也能触发函数。求大神指点！！！！！！！！！！
