Usage example


- (LFLiveSession*)session {
    if (!_session) {
        _session = [[LFLiveSession alloc] initWithAudioConfiguration:[LFLiveAudioConfiguration defaultConfiguration] videoConfiguration:[LFLiveVideoConfiguration defaultConfiguration]];
        _session.preView = self;
        _session.delegate = self;
    return _session;

  • (void)startLive { LFLiveStreamInfo *streamInfo = [LFLiveStreamInfo new]; streamInfo.url = @"your server rtmp url"; [self.session startLive:streamInfo]; }

  • (void)stopLive { [self.session stopLive]; }

//MARK: - CallBack:

  • (void)liveSession:(nullable LFLiveSession *)session liveStateDidChange: (LFLiveState)state;
  • (void)liveSession:(nullable LFLiveSession )session debugInfo:(nullable LFLiveDebug)debugInfo;
  • (void)liveSession:(nullable LFLiveSession*)session errorCode:(LFLiveSocketErrorCode)errorCode;


// import LFLiveKit in [ProjectName]-Bridging-Header.h

//MARK: - Getters and Setters lazy var session: LFLiveSession = { let audioConfiguration = LFLiveAudioConfiguration.defaultConfiguration() let videoConfiguration = LFLiveVideoConfiguration.defaultConfigurationForQuality(LFLiveVideoQuality.Low3, landscape: false) let session = LFLiveSession(audioConfiguration: audioConfiguration, videoConfiguration: videoConfiguration)

session?.delegate = self
session?.preView = self.view
return session!


//MARK: - Event func startLive() -> Void { let stream = LFLiveStreamInfo() stream.url = "your server rtmp url"; session.startLive(stream) }

func stopLive() -> Void { session.stopLive() }

//MARK: - Callback func liveSession(session: LFLiveSession?, debugInfo: LFLiveDebug?) func liveSession(session: LFLiveSession?, errorCode: LFLiveSocketErrorCode) func liveSession(session: LFLiveSession?, liveStateDidChange state: LFLiveState) </lflivekit.h>
