 3 | 
 4 | ### 实现原理：
 5 | 渐变图层 使用 CAGradientLayer实现
 6 | ![](http://oahmyhzk1.bkt.clouddn.com/image/pngGradient-circle-1.png)
 7 | 
 8 | ### 创建两个 CAGradientLayer 对象 
 9 | ![](http://oahmyhzk1.bkt.clouddn.com/image/pngGradient-circle-2.png)
10 | 
11 | 
12 | ### 根据圆的路径在图层上截取一个圆
13 | ![](http://oahmyhzk1.bkt.clouddn.com/image/pngGradient-circle-3.png)
14 | 
15 | 
16 | ### 使用 CABasicAnimation 让layer 动起来
17 | ![](http://oahmyhzk1.bkt.clouddn.com/%E6%B8%90%E5%8F%98%E5%9C%86loading.gif)
