#import <PPYLiveKit/PPYLiveKit.h>
                                

 PPYPushEngine *pushEngine = [[PPYPushEngine alloc]initWithAudioConfiguration:self.audioConfig
 andVideoConfiguration:self.videoConfig pushRTMPAddress:self.rtmpAddress];;
                                

参数配置：

• 音频

  
  PPYAudioConfiguration *audioConfigure = [PPYAudioConfiguration defaultAudioConfiguration];
                                          

• 视频

  
  PPYVideoConfiguration *videoConfigure = [PPYVideoConfiguration defaultVideoCOnfiguration];
                                          

• 支持音视频参数Level调解：

  
  +(instancetype)videoConfigurationWithVideoQuality:
  (PPYVideoQuality)videoQuality;
  +(instancetype)audioConfigurationWithAudioQuality:
  (PPYAudioQuality)audioQuality;
                                          

• 支持音视频参数自定义，可以调用：

  
  +(instancetype)audioConfigurationWithSamplerate:
  (PPYAudioSampleRate)samplerate andChannelCount:
  (int)channelCount andBirate:(PPYAudioBitRate)bitrate;
  +(instancetype)videoConfigurationWithPreset:
  (PPYCaptureSessionPreset)videoPreset andFPS:
  (PPYCaptureFPS)fps andBirate:(int)bitrate; //kbps
                                          

• 设置代理：

  
  pushEngine.delegate = self;
                                          

• 代理监听流状态，流信息，抛出异常

  
  -(void)didStreamStateChanged:(PPYPushEngineStreamStatus)status{
  }
  
  -(void)didStreamErrorOccured:(PPYPushEngineErrorType)error{
  }
  
  -(void)didStreamInfoThrowOut:(PPYPushEngineStreamInfoType)type infoValue:(int)value{
  }
                                          

• 建立视频预览：

  
  pushEngine.preview = self.view
                                          

• 开始视频预览：

  
  pushEngine.running = YES;
                                          

• 开始推流：

  
  [pushEngine start]
                                          

• 结束推流：

  
  [pushEngine stop];
                                          

• 切换摄像头：

  
  pushEngine.cameraPosition = AVCaptureDevicePositionFront;
  pushEngine.cameraPosition = AVCaptureDevicePositionBack;
                                          

• 闪光灯：

  
  pushEngine.torch = YES;
  pushEngine.torch = NO;
                                          

• 自动连续对焦：

  
  if(pushEngine.hasFocus){
      pushEngine.autoFocus = YES;
  }
  if(pushEngine.hasFocus){
      pushEngine.autoFocus = NO;
  }
                                          

• 手动对焦：

  
  CGPoint location = [touch locationInView:self.view];
  [pushEngine doFocusOnPoint:location onView:self.view needDisplayLocation:YES];
                                          

• 美颜三档参数可调，调节范围0～1.0：

  
  pushEngine.beautify = YES;
  pushEngine.beautyLevel = 0.5;
  pushEngine.brightLevel = 0.5;
  pushEngine.toneLevel = 0.5;
                                          

• 静音开关：

  
  pushEngine.mute = YES;
