30天学习Swift项目实战第四天------滑动菜单（UIScrollView）

概述注意：项目分为3个界面，中间的界面使用了摄像头，模拟器是不能完成的。 源码分为4个文件： ViewController.swift: // // ViewController.swift // SlideMenu // // Created by luopan on 16/8/5. // Copyright © 2016年 Hust University. All rights reserved.

}

最后，我们有四个界面设计的文件。UIImageVIEw是没有用户交互功能是的，但是可以用一个UIVIEw来覆盖并设置用户交互属性就可以达到效果。

注意：所有的源码都可以找QQ是709165253的人要。 索要源码的时候，最好说明是在开源中国看到的。
