iphone - 在iPhone SDK上播放mp3吗？

Question

-(IBAction)musiconButtonClicked:(id)sender{
    NSString *path = [[NSBundle mainBundle] pathForResource:@"NextRevIt" ofType:@"mp3"];
    AVAudioPlayer* audioPlayer = [[AVAudioPlayer alloc ] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
    [audioPlayer play];
}


-(IBAction)musicoffButtonClicked:(id)sender{
    [audioPlayer stop]; <----says this is undeclared?
}

我可以使音频正常播放，但是如何制作一个停止音频的按钮？

Answer 1

将其放在interface的.h块中。

AVAudioPlayer* audioPlayer;

您将需要检查实例并释放它。
