MPMoviePlayer 잠금 화면 오디오 재생/일시 중지

Question

MPMoviePlayer를 통해 스트리밍 오디오를 실행 중입니다. 원격 이벤트를 잠금 화면 및 독에 전송하여 제목과 작성자를 볼 수있게하고 배경 모드에서 오디오를 재생할 수 있지만 나에게있어 잠금 화면/독 재생 버튼을 시작하고 재생할 수는 없습니다. 오디오를 멈추십시오. 완전히 빠진 것이 있습니까?

당신은 당신이 실제로 원격 제어 이벤트를 수신하는 코드에있는 표시되지 않는 :

여기 내 코드입니다. 다음과 같음 :

- (void)remoteControlReceivedWithEvent:(UIEvent *)receivedEvent 
{ 
    if (receivedEvent.type == UIEventTypeRemoteControl) { 
     switch (receivedEvent.subtype) { 
      case UIEventSubtypeRemoteControlPlay: 
      case UIEventSubtypeRemoteControlPause: 
      case UIEventSubtypeRemoteControlStop: 
      case UIEventSubtypeRemoteControlTogglePlayPause: 
       if (self.player.isPlaying) { 
        [self.player pause]; 
        [[MPMusicPlayerController applicationMusicPlayer] pause]; 
       } else { 
        [self.player play]; 
        [[MPMusicPlayerController applicationMusicPlayer] play]; 
       } 
       break; 

      case UIEventSubtypeRemoteControlBeginSeekingBackward: 
      case UIEventSubtypeRemoteControlBeginSeekingForward: 
      case UIEventSubtypeRemoteControlEndSeekingBackward: 
      case UIEventSubtypeRemoteControlEndSeekingForward: 
      case UIEventSubtypeRemoteControlPreviousTrack: 
      case UIEventSubtypeRemoteControlNextTrack: 
       self.player.currentTime = 0; 
       break; 

      default: 
       break; 
     } 
    } 
}
