单点触摸：

    auto label = LabelTTF::create("Label", "Courier", 30);    label->setPosition(visibleSize / 2);    this->addChild(label);    auto listener = EventListenerTouchOneByOne::create(); /*创建事件侦听*/    listener->onTouchBegan = [](Touch *touch, Event* event){ /*开始点击触发回调函数*/        if (event->getCurrentTarget()->getBoundingBox().containsPoint( /*触摸点是否在目标范围*/            touch->getLocation())){            CCLOG("OK");        }        return false;  /*事件是否传递  false不传递，true传递*/    };    /*在场景中注册事件*/    Director::getInstance()->getEventDispatcher()->         addEventListenerWithSceneGraphPriority(listener, label);

多点触摸：

    auto listener = EventListenerTouchAllAtOnce::create();    listener->onTouchesBegan = [](std::vector<Touch*> touchs, Event* event){        CCLOG("Touchs Began!");    };    listener->onTouchesMoved = [](std::vector<Touch*> touchs, Event* event){        CCLOG("Touchs Move: %d", touchs.size());    };    Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listener, this);
