iOS 推流LFLiveKit
关于直播推流所用到的是LFLiveKit这个第三方框架.可以说大神们已经给我们继承好了所有的麻烦,我们只需要调用相关接口就可以了.
只是将自己踩过的坑记下来，希望众位能顺利一些。
关于LFLiveKit如何集成，这个很简单
CocoaPods
- pod search LFLiveKit
- pod install
- 直接导入即可
- 非要任性自己导入，那就看天命吧！祝你好运
#import<LFLiveKit/LFLiveKit.h>
#import"LFLiveKit.h"
#import<IJKMediaFramework/IJKMediaFramework.h>

@interface start_ViewController ()<LFLiveSessionDelegate>
//当前区域网所在IP地址
@property (nonatomic,copy) NSString *ipAddress;
//我的房间号
@property (nonatomic,copy) NSString *myRoom;
//别人的房间号
@property (nonatomic,copy) NSString *othersRoom;
//ip后缀(如果用本地服务器,则为在nginx.conf文件中写的rtmplive)
@property (nonatomic, copy) NSString *suffix;
//大视图
@property (nonatomic,weak) UIView *bigView;
//小视图
@property (nonatomic,weak) UIView *smallView;
//播放器

//推流会话

步入正题

IJKMediaFramework/IJKMediaFramework.h关于这个库没找到的问题,这是一个第三方播放器,网上有很多的集成帖子,自己看看就能集成,然后拉到工程中就可以了我使用它播放自己的直播,那断代码我就不发了,和推流不相关,就不跑题了.反正在推流中用不到,拉流才能用到,
下载 VLC 也可以,也可以看自己的推流.不想用就自己直接删掉吧,写上是为了方便大家查找.少踩点坑
由于本人用的是本地服务器，截图异常的丑，不不嘚瑟了
有什么问题欢迎大家留言指正,我看到一定回复.感谢!!!!!!!
