| // iOS动画应用内处理的4个阶段 | |
| 在iOS中，动画的执行主要分6个阶段，其中4个阶段是在应用内部处理的： | |
| Layout: 这一阶段是准备好view/layer的层级结构并设置layer的属性； | |
| Display: 这一阶段将绘制layer的内容。绘制操作会调用-drawRect:或-drawLayer:inContext:方法； | |
| 准备阶段: 这一阶段是Core Animation准备将动画数据发送给render server。另外，还会执行其它一些操作，如解压在动画过程中显示的图片； | |
| 提交: 这是应用内部处理的最后一个阶段，Core Animation将打包layer及动画属性并通过IPC发送到render server； | |
| 这几个阶段都是由CPU来处理的，而且我们只能控制前面两个阶段，后两个阶段将由Core Animation来控制。 |
