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 上，当我的应用触发一个简短的 wav 文件以使用 AVAudioPlayer 播放时，音乐会暂停.这是正常的吗?
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?
我找不到对此的任何参考，而且似乎会在某处注明.有没有办法在我播放声音时让音乐继续播放?
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?
推荐答案
如果不做更多工作，您就无法同时运行 AVAudioPlayer 和 iPod 播放器或 MPMusicPlayer 或 MPMoviePlayer.如果您想要轻松，请使用 Audio Toolbox 的系统声音.
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.
如果你想做一些额外的工作，那么你应该看看音频会话:
If you want to do some extra work, then you should look at Audio Sessions:
kAudioSessionCategory_UserInterfaceSoundEffects对于声音效果，如触摸反馈、爆炸等等.
kAudioSessionCategory_UserInterfaceSoundEffectsFor sound effects such as touch feedback, explosions, and so on.
相当于kAudioSessionCategory_AmbientSound您应该使用的类别反而.这kAudioSessionCategory_UserInterfaceSoundEffects类别在 iPhone 操作系统中已弃用3.0.
Equivalent to the
kAudioSessionCategory_AmbientSound
category, which you should use
instead. The
kAudioSessionCategory_UserInterfaceSoundEffects
category is deprecated in iPhone OS
3.0.
kAudioSessionCategory_AmbientSound 对于长时间的声音，如雨、汽车发动机噪音等等.也是对于一起玩"风格的应用程序，用户弹奏的这种虚拟钢琴通过 iPod 音频.
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.
当您使用此类别时，音频来自内置应用程序，例如iPod，与您的音频混合.你的响铃/静音时音频静音开关设置为静音或当屏幕锁定.
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.
