推荐答案

您可以使用不同的类别来执行此操作：

You can use different categories to do this:

- (void)applicationDidFinishLaunching:(UIApplication *)application
{  
    ...

     // allows you to play when the screen is locked and also when the ringer is set to silent
    [[AVAudioSession sharedInstance] setDelegate: self];
    [[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error:nil];

    ...
}

如果你想继续当您的应用程序被暂停到后台时（例如，用户点击主页按钮）在iOS4上播放声音，然后您还需要将其添加到 info.plist 文件（以纯文本模式显示）：

If you want to continue to play the sound on iOS4 when your app gets suspended into the background (for instance, the user hits the home button), then you also need to add this to your info.plist file (this shows it in plain text mode):

<key>UIBackgroundModes</key>
<array>
    <string>audio</string>
</array>

顺便说一句，如果你真的需要处理像这样的中断您的问题标题说（如电话等），在 AVAudioPlayer class ：

By the way, if you ever really needed to handle an interruption like your question title said (like a phone call, etc), there is a delegate method for that in the AVAudioPlayer class:

- (void) audioPlayerBeginInterruption: (AVAudioPlayer *) player { }

和

- (void) audioPlayerEndInterruption: (AVAudioPlayer *) player { }
