    //创建监听器
    auto listen = EventListenerTouchOneByOne::create();
    listen->setSwallowTouches(false);
    listen->onTouchBegan = [](Touch* touch, Event* event){
        auto target = static_cast<Sprite*>(event->getCurrentTarget());
        if(target->getBoundingBox().containsPoint(touch->getLocation()))
        {
            return true;
        }
        return false;
    };
    listen->onTouchMoved = [](Touch* touch,Event* event){
        // 获取事件所绑定的 target
        auto target = static_cast<Sprite*>(event->getCurrentTarget());
        if (target->getBoundingBox().containsPoint(touch->getLocation())) {
            target->setPosition(target->getPosition() + touch->getDelta());
        }
    };
    listen->onTouchEnded = [=](Touch* touch, Event* event){};
