Question

我正在开发一个iphone应用程序，我正在使用MPMoviePlayerViewController播放流音频。使用以下代码，它工作正常。

moviePlayerController = [[MPMoviePlayerViewController alloc] initWithContentURL:fileURL];
[moviePlayerController.view setFrame:CGRectMake(0, 83, 1024, 400)];
   moviePlayerController.moviePlayer.controlStyle = MPMovieControlModeVolumeOnly;
[moviePlayerController.moviePlayer prepareToPlay];
    moviePlayerController.moviePlayer.shouldAutoplay=YES;
   [moviePlayerController.moviePlayer play];

但是当播放播放器中有通话时，它会停止。我希望在收到电话后恢复播放器流媒体歌曲。我怎样才能做到这一点？

任何建议都会受到赞赏。

Answer 1

使用 NSNotificationCenter 为其注册通知。因此，当应用程序到达前台时，您可以恢复播放。这是处理任何ios应用程序此类事件的正确方法。

有关更多信息，请参阅NSNotificationCenter Class Reference on apple docs

您也可以refer this了解要遵循的具体步骤。

Answer 2

您可以使用在应用程序委托类

中实现的方法

- (void)applicationDidBecomeActive:(UIApplication *)application {

// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}

Answer 3

根据您的情况尝试这些方法......

-(void)audioPlayerBeginInterruption:(AVAudioPlayer *)audioPlayer;
{
    [self.audioPlayer pause];
}

-(void)audioPlayerEndInterruption:(AVAudioPlayer *)audioPlayer;
{
    [self.audioPlayer play];
}
