我正在研究一個簡單的聲卡應用程序，只要按下按鈕，它就會播放相應的聲音。然而，我似乎並沒有正確地發佈我的變量（或者現在，因爲我將代碼恢復到播放聲音的地方，但存在內存泄漏），我知道它不符合應用商店標準。我需要弄清楚如何解決這個問題，所以任何幫助表示讚賞！簡單的Soundboard應用程序中的iOS AudioPlayer內存泄漏

我已經試過各種方法推（pushTropical，pushBurnHouse等內釋放 'theAudio' 變量）像這樣...
-(IBAction)pushExcited {
NSString *path = [[NSBundle mainBundle]
pathForResource:@"dukesIsExcited" ofType:@"m4a"];
AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
theAudio.delegate = self;
[theAudio play];
[theAudio release];
}
...但是，然後聲音拒絕播放。所以我不知所措，因爲每當我嘗試在這些功能中的任何地方釋放「音頻」時，它都不會識別它釋放它。幫幫我！
