安装

CocoaPods

# To integrate LFLiveKit into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '7.0'
pod 'LFLiveKit'

# Then, run the following command:
$ pod install

Carthage

1. Add `github "LaiFengiOS/LFLiveKit"` to your Cartfile.
2. Run `carthage update --platform ios` and add the framework to your project.
3. Import \<LFLiveKit/LFLiveKit.h\>.

手动方式

1. Download all the files in the `LFLiveKit` subdirectory.
2. Add the source files to your Xcode project.
3. Link with required frameworks:
    * UIKit
    * Foundation
    * AVFoundation
    * VideoToolbox
    * AudioToolbox
    * libz
    * libstdc++

使用示例

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)
