如何使用AVAudioPlayer发布声音？

Question

我正在尝试使用AVFoundation框架创建一个带有很多按钮的“互动式采访”音板。音板完成，但我有一个问题，当我按下我的一个声音时，它不会停止，当我同时按下一个新的。如果按下新的声音，是否有简单的方法来停止以前的声音？我的代码看起来像这样

- (IBAction)playSound0 { 
    NSString *path = [[NSBundle mainBundle] pathForResource:@"about" ofType:@"mp3"]; 
    AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; 

    [theAudio play]; 
} 

- (IBAction)playSound1 { 
    NSString *path = [[NSBundle mainBundle] pathForResource:@"chillwhatup" ofType:@"mp3"]; 
    AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; 

    [theAudio play]; 
} 

- (IBAction)playSound2 { 
    NSString *path = [[NSBundle mainBundle] pathForResource:@"gethighorgetlow" ofType:@"mp3"]; 
    AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; 

    [theAudio play]; 
} 

- (IBAction)playSound3 { 
    NSString *path = [[NSBundle mainBundle] pathForResource:@"icamefromthere" ofType:@"mp3"]; 
    AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; 

    [theAudio play]; 
} 

- (IBAction)playSound4 { 
    NSString *path = [[NSBundle mainBundle] pathForResource:@"idoeverythinggood" ofType:@"mp3"]; 
    AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; 


    [theAudio play]; 

}

我只想有我的课跟踪上次启动的声音，在此之前我开始玩一个新的声音，停止以前的一个，如果它仍然在播放。

AVAudioPlayer有停止方法停止声音和打方法，看它是否被打。
