嗨,我想用AVAudioPlayer和基礎播放很多聲音。 的代碼是這個播放多個聲音時出現Objective C錯誤

- (IBAction)pushButton19 { 
    NSString *path = [[NSBundle mainBundle] pathForResource:@"The Terminator" ofType:@"mp3"]; 
    AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; 
    theAudio.delegate = self; 
    [theAudio play]; 
} 

- (IBAction)pushButton20 { 
    NSString *path = [[NSBundle mainBundle] pathForResource:@"The Wizard of Oz" ofType:@"mp3"]; 
    AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; 
    theAudio.delegate = self; 
    [theAudio play]; 
} 

上線theAudio.delegate = self; 它說

類*沒有實現 協議

以及

語義問題分配t ØID 從 不兼容的類型的MainView *

什麼我需要做修復它和u能告訴我正確的代碼作爲這個我是個菜鳥?
