iphone - 如果打开静音模式如何停止播放声音

Question

我的代码:

NSString *soundName = [[NSBundle mainBundle] pathForResource:@"music" ofType:@"mp3"];
NSURL *soundURL = [NSURL fileURLWithPath:soundName];
NSError *error = [[NSError alloc] init];
self.backgroundPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundURL error:&error];

if (self.backgroundPlayer == nil) {
    NSLog(@"error = %@",[error description]);
} else {
    [self.backgroundPlayer setDelegate:self];
    [self.backgroundPlayer setNumberOfLoops:HUGE_VAL];
    [self.backgroundPlayer setVolume:0.5f];
    [self.backgroundPlayer prepareToPlay];
    if ([self.backgroundPlayer prepareToPlay]) {
        if ([self.backgroundPlayer play]) {
            NSLog(@"playing");
        }
    } else {
        NSLog(@"error!");
    }
}

当我将 iPhone 切换到静音模式时，声音仍在播放。我该如何解决这个问题？

我没试过，但是你可以在播放文件之前设置音频类别:

[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategorySoloAmbient error:nil];
