iPhone AVAudioPlayer停止背景音乐 [英] iPhone AVAudioPlayer stopping background music

问题描述

所以，我刚刚注意到在我的iPod Touch，当我的应用程序触发短WAV文件中使用AVAudioPlayer播放，音乐被暂停。这正常吗？

我找不到这个任何提及，似乎像它会在某个地方注明。有没有一种方法来继续播放音乐，而我发挥我的声音？

解决方案

  

注意：<一href=\"https://developer.apple.com/library/ios/documentation/AudioToolbox/Reference/AudioSessionServicesReference/\"相对=nofollow>的AudioSession API已经完全去$ P $ iOS中pcated 7.0

您不能在同一时间运行AVAudioPlayer和iPod播放器或MPMusicPlayer或MPMoviePlayer，没有做一点更多的工作。如果你想轻松，然后使用音频工具箱的系统声音。

如果你想要做一些额外的工作，那么你应该看看<一个href=\"http://developer.apple.com/iphone/library/DOCUMENTATION/AudioToolbox/Reference/AudioSessionServicesReference/Reference/reference.html\"相对=nofollow>音频会话：

  

kAudioSessionCategory_UserInterfaceSoundEffects
  用于音响效果诸如触摸
  反馈，爆炸，等等。

  
  

等价于
   kAudioSessionCategory_AmbientSound
  类，你应该使用
  代替。该
   kAudioSessionCategory_UserInterfaceSoundEffects
  类是德precated在iPhone OS
  3.0。

当你使用这个类，从声音

So I've just noticed that on my iPod Touch, when my app triggers a short wav file to play using AVAudioPlayer, the music gets paused. Is this normal?

I can't find any reference to this, and it seems like it would be noted somewhere. Is there a way to keep the music going while I play my sounds?

解决方案

Note: The AudioSession API has been completely deprecated in iOS 7.0

You can't run AVAudioPlayer and the iPod player or MPMusicPlayer or MPMoviePlayer at the same time, without doing a bit more work. If you want easy, then use Audio Toolbox's System Sounds.

If you want to do some extra work, then you should look at Audio Sessions:

kAudioSessionCategory_UserInterfaceSoundEffects For sound effects such as touch feedback, explosions, and so on.

Equivalent to the kAudioSessionCategory_AmbientSound category, which you should use instead. The kAudioSessionCategory_UserInterfaceSoundEffects category is deprecated in iPhone OS 3.0.

kAudioSessionCategory_AmbientSound For long-duration sounds such as rain, car engine noise, and so on. It is also for "play along" style applications, such a virtual piano that a user plays over iPod audio.

When you use this category, audio from built-in applications, such as the iPod, mixes with your audio. Your audio is silenced when the Ring/Silent switch is set to silent or when the screen locks.
