[原]关于在 iOS 中支持 DLNA

目前国内的视频播放器中，支持 DLNA 播放比较好的是：腾讯视频。

刚才反编了一下他们的代码，发现使用了一个开源库，

地址：https://github.com/FuruyamaTakeshi/DLNA

并且在这个库的基础了做了一层封装，包含如下几个类：

DLNAController:

 1 @class CGUpnpAvController, CGUpnpAvRenderer, QLUpnpAVVolumeInfo, NSMutableArray, QLUpnpAVPositionInfo, NSString, NSTimer;
 2 @protocol DLNAControllerDelegate;

找时间阅读下汇编代码，写出一个开源版本。^_^
