cocos2d-x 2.2 study    ----------    长按事件处理

其实是在点击事件发生的时候，

在开始的时候添加一个一次的计时器，

在计时器中添加方法，

在结束的时候将添加的内容移除掉

代码：(主要代码)

void    GetFirstRechargePackLayer::menuEvent(CCObject* pSender, cocos2d::ui::TouchEventType type)
{
    switch (type)
    {
    case TOUCH_EVENT_BEGAN:
        {
            if ( pSender == m_pImage4)
                m_materialType = EP_HERO;
            else
                m_materialType = EP_ITEM;
            m_isLongClick = false;
            m_icon = pSender;
            touchBeginPoint = ((cocos2d::ui::UIImageView*)pSender)->getTouchStartPos();
            this->scheduleOnce(schedule_selector (GetFirstRechargePackLayer::createTipLayer),0.2);
        }
        break;
    case TOUCH_EVENT_MOVED:
        {
            touchMovedPoint = ((cocos2d::ui::UIImageView*)pSender)->getTouchMovePos();
            float distance = sqrt((touchMovedPoint.x-touchBeginPoint.x) * (touchMovedPoint.x-touchBeginPoint.x) + (touchMovedPoint.y-touchBeginPoint.y)*(touchMovedPoint.y-touchBeginPoint.y));

            if (distance >= 50)
            {
                this->unschedule(schedule_selector (GetFirstRechargePackLayer::createTipLayer));
            }
        }
        break;
    case TOUCH_EVENT_ENDED:
        {
            this->unschedule(schedule_selector (GetFirstRechargePackLayer::createTipLayer));
            if (m_isLongClick == true)
            {
                this->removeChild(m_pLayerTips);
            }
        }
        break;
    case TOUCH_EVENT_CANCELED:
        {

            {
                this->removeChild(m_pLayerTips);
            }
        }
        break;
    default:
        break;
    }
}

void GetFirstRechargePackLayer::createTipLayer(float dt)
{
    m_isLongClick = true;
    // 参数：1->图片(所点击的那个图片)，2->类型(图片的类型)，3->id
    m_pLayerTips = DesriptionTips::create(m_icon,m_materialType,(long)((cocos2d::ui::UIImageView*)m_icon)->getUserData());
    
    this->addChild(m_pLayerTips);
