当应用程序进入后台时,我在播放音频流时遇到麻烦.
I am running into trouble with playing an audio stream when the application enters background.
我使用代码启动流:
NSURL *mediaURL = [NSURL URLWithString:@"url.to.my.stream"]; MPMoviePlayerController *mp = [[MPMoviePlayerController alloc] initWithContentURL:mediaURL]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil]; [mp setControlStyle:MPMovieControlStyleFullscreen]; [mp setMovieSourceType:MPMovieSourceTypeStreaming]; [mp setFullscreen:YES]; [self.view addSubview:[mp view]]; [mp prepareToPlay]; [mp play];效果完美.但尽管如此,当应用程序进入后台时,我会在属性列表中设置应用程序播放音频"标记,流将停止播放.
It works perfect. But allthough I set the flag 'App plays audio' in the property list when the app enters background the stream stops playing.
如何使我的应用程序在后台播放音频流?
How do I make my application play the audio stream in the background?
最诚挚的问候,非常感谢您的帮助!
Best regards and thanks a lot for help!
推荐答案我自己没有尝试过,但这看起来很有希望: iOS多任务处理:背景音频
I didn't tried it myself but this looks promising: iOS Multitasking: Background Audio
创建项目后,转到APP-Info.plist并添加 UIBackgroundModes作为新行.然后应该创建数组.
Once the project has been created go to APP-Info.plist and add UIBackgroundModes as a new row. It should then create the array.
打开数组,然后在Item 0的右侧将其设置为音频.
Open the array and to the right of Item 0 set it to audio.

您的AVAudioSession是否设置正确?
Is your AVAudioSession set up properly?
AVAudioSession *audioSession = [AVAudioSession sharedInstance]; [audioSession setCategory:AVAudioSessionCategoryPlayback error:nil]; [audioSession setActive:YES error:nil];更多推荐
