如何解決此代碼泄漏（啓用ARC）？

Question

這裏是我的代碼（啓用ARC），可以看到內存泄漏。

請幫我解決這個問題。

- (void) setMusic 
{  
    /* 
    Initialise and set the music for the game. 
    */ 

NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"actionMusic" ofType:@"caf"]]; 
NSError *error = nil; 
_audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error]; 
if (!error) 
{ 
    _audioPlayer.delegate = self; 
    if(_musicFlag) 
    { 
     [_audioPlayer play]; 
    } 
    [_audioPlayer setNumberOfLoops:INT32_MAX]; 
} 

error = nil; 
url =nil; 

url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"pew" ofType:@"wav"]]; 
_moveMusic = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error]; 

if (!error) 
{ 
    _audioPlayer.delegate = self; 
} 

error = nil; 
url =nil; 


url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"Won" ofType:@"wav"]]; 
_winningMusic = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error]; 

if (!error) 
{ 
    _winningMusic.delegate = self; 
    [_winningMusic setNumberOfLoops:1]; 
} 

} 

Answer 1

我發現泄漏的答案。

此漏洞歸因於AVAudioPlayer基礎類，它尚未由Apple修復。

因此使用AVAudioPlayer基礎類導致泄漏。
