iphone - AVAudioPlayer 泄漏？

Question

我遇到了一个问题，不知道如何处理。尝试构建带有声音和动画的应用程序。它给了我 1 级和 2 级内存警告。我试过构建和分析，发现了所有这些潜在的漏洞。如果我释放 theAudio，声音将不会播放。有什么提示吗？

这是部分代码和我得到的漏洞

    - (IBAction)playsound2
    {
        NSString *path = [[NSBundle mainBundle] pathForResource:@"cat" ofType:@"mp3"];
        AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; 
        *- **Method returns an Objective-C object with a +1 retain count (owning reference)***
        theAudio.delegate = self;
        [theAudio play];

        ***-  Object allocated on line 302 and stored into 'theAudio' is no longer referenced after this point and has a retain count of +1 (object leaked)***


        cat1.hidden = 0;
        cat.hidden = 1;
        [cat1 startAnimating];
        cat.center = cat1.center;
        [self performSelector:@selector(loadAnimations) withObject:nil afterDelay:1.0];
        catLabel.hidden = 0;
    }

Here是迄今为止提出的同一问题的解决方案。

    - (AVAudioPlayer *)audioPlayerWithContentsOfFile:(NSString *)path {
        NSData *audioData = [NSData dataWithContentsOfFile:path];
        AVAudioPlayer *player = [AVAudioPlayer alloc];
        if([player initWithData:audioData error:NULL]) {
            [player autorelease];
        } else {
            [player release];
            player = nil;
        }
        return player;
    }
