我正在开发一个简单的音板应用程序，每当您按下一个按钮，它就会播放相应的声音。但是，我似乎并没有正确释放变量（或者说从现在开始，因为我将代码恢复到可以播放声音但内存泄漏的位置），并且我知道它不符合应用商店的标准。我需要弄清楚如何解决此问题，以便对您有所帮助！
我的ViewController.h是：
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#import <AVFoundation/AVAudioPlayer.h>
@interface FirstViewController : UIViewController <AVAudioPlayerDelegate>

我试过像这样在各种推送方法（pushTropical，pushBurnHouse等）中释放“ theAudio”变量。
-(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，声音完全无法播放。所以我很茫然，因为无论何时我尝试在那些功能之外的任何地方释放“ theAudio”，它都不会识别它来释放它。救命！
最佳答案
将类设置为委托后，应通过audioPlayerDidFinishPlaying:successfully: AVAudioPlayerDelegate方法释放AVAudioPlayer。
即：
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag {
[player release];
}
完成此操作后，一切都会很好。
