iOS 制作基于pod开发第三方framework的二次封装

主要记录如何将第三方SDK的.a或framwwork集成到自己的framework中，并构建自己的pod发布到私有库所遇到的问题。

集成

1. 打开第三方SDK找到二进制文件（以iflyMSC.framework为例）
2. 将iflyMSC的二进制文件改成.a的后缀名，重命名为libiflyMSC.a。 如果不加lib前缀，那么在后面进行pod lib lint命令时有可能会遇到这样的错误提示：

AVPlayer Background Design

1. 使用NSNotification来监听进入后台和前台事件

   .UIApplicationWillEnterForeground .UIApplicationDidEnterBackground

2. 长按home键不会响应 1. 中的两个通知事件，需要同时使用以下通知

   .UIApplicationWillResignActive .UIApplicationDidBecomeActive
