ios 添加音频到按钮

Question

嗨，有人知道如何向按钮添加音频吗？我已经添加了框架，创建了一个放置声音的 Action ，但是当我按下按钮时没有声音播放？

这是我到目前为止所做的

-(void)buttonSound{


    NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/ButtonSound.mp3", [[NSBundle mainBundle] resourcePath]]];

    NSError *error;
    audioPlayer2 = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
    audioPlayer2.numberOfLoops = -1;

    [audioPlayer2 play];

}

- (IBAction)backToMenu:(id)sender {
    [self buttonSound];
    [self.navigationController popViewControllerAnimated:YES];
}

对于简短的系统声音，你应该使用类似的东西:

SystemSoundID sound;
CFURLRef alertURL = CFBundleCopyResourceURL(CFBundleGetMainBundle(), (CFStringRef)@"ButtonSound", CFSTR("mp3"), NULL);
OSStatus status = AudioServicesCreateSystemSoundID(alertURL, &sound);

AudioServicesPlayAlertSound(sound);
