我想在后台播放音频 HTTP 直播流。但我该怎么做呢？
我尝试将值为“audio”的键（数组）“UIBackgroundModes”添加到 info.plist 中。现在我尝试使用 MPMoviePlayerController 播放音频。但一旦应用程序进入后台，音频播放就会停止！我不知道还有什么其他 API 可以在 iPhone 上播放 HTTP Live Stream。那么还有其他的还是我做错了什么？
我搜索了所有苹果文档，但找不到任何有用的东西。文档中没有太多关于背景音频的内容:-(
I'd like to play an audio HTTP Live Stream in background. But how do I do that?
I tried to add the key (an Array) "UIBackgroundModes" with value "audio" to the info.plist. Now I try to play audio with the MPMoviePlayerController. But as soon as the app goes into background, the audio Playback stops! I don't know of any other API to play a HTTP Live Stream on the iPhone. So is there an other or am I doing something wrong?
I searched all over the apple documentation but couldn't find anything useful. There isn't much about background audio in the docs :-(

请参阅 http://developer.apple.com/iphone/library/qa /qa2010/qa1668.html 了解 iOS4 中的更改以及如何实现您想要的功能。
这在我的一个应用程序中适用于我。
See http://developer.apple.com/iphone/library/qa/qa2010/qa1668.html for a description of what changed in iOS4 and how to implement the functionality you want.
This works for me in one of my apps.
找到了解决方案：
在 MPMoviePlayerController 上将
useApplicationAudioSession设置为NO即可完成这项工作。但它仅适用于纯音频流。视频流仍然停止。Found a soluton:
setting
useApplicationAudioSessiontoNOon the MPMoviePlayerController does the job. But it works only on audio only streams. Video streams still stop.将音频会话类别设置为 kAudioSessionCategory_MediaPlayback 可能有效。
Setting your audio session category to kAudioSessionCategory_MediaPlayback might work.
