2. Add the source files to your Xcode project.
3. Link with required frameworks:
    * UIKit
    * Foundation
    * AVFoundation
    * VideoToolbox
    * AudioToolbox
    * libz
    * libstdc++

Usage example

Objective-C

- (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;

Swift

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