详解IOS开发之动画开发

APP的开发因为动画的展现变得更加的酷炫,项目的开发最重要是取决于用户体验,别着急下面是云上诗词技术频道小编和大家分享的详解IOS开发之动画开发,大家可以参考下文学习一下。

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 。

代码很简单,直接贴了,如下:
