AVAudioPlayer泄漏? [英] AVAudioPlayer leaks?

问题描述

我遇到了一个问题，不知道如何处理.尝试用声音和动画构建应用程序.它给了我1级，然后2级的内存警告.我尝试构建和分析，但发现了所有这些潜在的漏洞.如果我释放Audio，声音将不会播放.有什么提示吗?

I've got a problem and don't know how to handle it. Tyring to build an app with sound and animation. It gives me a level 1 and then level 2 memory warning. I've tried build and analyze and i got all these potential leaks. If I release theAudio the sound won't play. Any hints?

这是代码的一部分，也是我所泄漏的内容

Here is a part of the code and the leakes I've got

    - (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;
    }

推荐答案

是到目前为止所问相同问题的解决方案.

Here is the solution for the same problem asked so far.

    - (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;
    }
