1.首先头文件定义事件处理的函数原型
private:
bool onTouchBegan(Touch* tTouch,Event* eEvent);//手指按下事件
void onTouchMoved(Touch* tTouch,Event* eEvent);//手指移动事件
void onTouchEnded(Touch* tTouch,Event* eEvent);//手指离开事件

2.实现原型
bool ShopItem::onTouchBegan(Touch* tTouch,Event* eEvent){
if (sprite->getBoundingBox().containsPoint(tTouch->getLocation())){//判断触摸点是否在目标的范围内

/**这里为事件内容**/
return true;
}else
return false;
}
}

void ShopItem::onTouchMoved(Touch* tTouch,Event* eEvent){
/**这里为事件内容**/
}

void ShopItem::onTouchEnded(Touch* tTouch,Event* eEvent){
/**这里为事件内容**/
}

3.绑定事件
auto listener = EventListenerTouchOneByOne::create();
listener->onTouchBegan = CC_CALLBACK_2(ShopItem::onTouchBegan, this);
listener->onTouchMoved = CC_CALLBACK_2(ShopItem::onTouchMoved, this);
listener->onTouchEnded = CC_CALLBACK_2(ShopItem::onTouchEnded, this);
this->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listener, sprite);
