想了解IOS 开发之UIView动画的实例详解的相关内容吗,Hi_Aaron在本文为您仔细讲解IOS UIview动画的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:IOS,UIView动画,IOS,动画,IOS,UIView,下面大家一起来学习吧。

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:
