关于在 iOS 中支持 DLNA

预览

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; 3 
 4 @interface DLNAController : XXUnknownSuperclass <CGUpnpControlPointDelegate> { 5 @private
 6     dispatch\_queue\_s\* \_playQueue;    // 4 = 0x4
 7     dispatch\_queue\_s\* \_searchQueue;    // 8 = 0x8
 8     CGUpnpAvRenderer\* \_dlnaPlayingRender;    // 12 = 0xc
 9     CGUpnpAvRenderer\* \_dlnaSelectedRender;    // 16 = 0x10
10     CGUpnpAvController\* \_upnpAvController;    // 20 = 0x14
11     NSMutableArray\* \_dlnaRenders;    // 24 = 0x18
12     NSTimer\* \_timerLoadInfos;    // 28 = 0x1c
13     BOOL \_isSettingVolume;    // 32 = 0x20
14     BOOL \_isSettingSeek;    // 33 = 0x21
15     id<DLNAControllerDelegate> delegate;    // 36 = 0x24
16     float \_trackDuration;    // 40 = 0x28
17     float \_curPlayTime;    // 44 = 0x2c
18     float \_volumePercentage;    // 48 = 0x30
19     NSString\* \_curRenderName;    // 52 = 0x34
20     unsigned \_fileSize;    // 56 = 0x38
21     QLUpnpAVPositionInfo\* \_positionInfo;    // 60 = 0x3c
22     QLUpnpAVVolumeInfo\* \_volumeInfo;    // 64 = 0x40
23     NSString\* \_curTitle;    // 68 = 0x44
24 }
25 @property(retain) QLUpnpAVPositionInfo\* positionInfo;    // G=0x1ecead; S=0x1ecec5;
