  做什么事都的持之以恒， 距离我写第一篇博文已经过了2天了.   我果然是比较懒的， 哈哈  博文地址:

CCProgressTimer， 先看效果：

实现这个效果很简单：

CCProgressTimer* pt = CCProgressTimer::create(CCSprite::create("Icon-72.png"));
    pt->setType( kCCProgressTimerTypeRadial );  //设置状态,我cocos2d-x版本2.13 
    this->addChild(pt);
    pt->setPosition( ccp(size.width/2, size.height/2) );
    pt->runAction(CCProgressTo::create(3, 100)); //CCProgressTo::create() 第一个参数为持续时间， 第二个参数为最后图像的百分比
    
    
    //type
    typedef enum {
        /// Radial Counter-Clockwise
        kCCProgressTimerTypeRadial,
        /// Bar
        kCCProgressTimerTypeBar,
    } CCProgressTimerType;

相信大家看的这里肯定心里不是滋味， 哈哈 。 就这么点，还要你说啊。 下面我带大家进入实战项目，演练一个， 还是拿我手上的这个棋牌项目来做例子

一样，先来看看效果。

下班了，大家等等哈。

继续，  直接上代码吧
