IOS开发之UIView动画的示例分析-创新互联
这篇文章将为大家详细讲解有关IOS开发之UIView动画的示例分析，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。
IOS 动画实例详解
iOS动画的实现方式多种多样，这里就只记录一下 beginAnimations:context 。
在你调用 beginAnimations:context:方法来启动一个动画后,动画并不会立即被执行,直 到你调用 UIView 类的 commitAnimations 类方法。你对一个视图对象执行的介于 beginAnimations:context:方法跟 commitAnimations方法之间的操作(例如移动)会在 commitAnimations 被执行后才会生效 。
实现效果图：
代码很简单，直接贴了，如下：
