iphone - AVAudioPlayer 没有声音输出

Question

我已将音频工具箱和 avfoundation 导入到我的类(class)中，并将框架添加到我的项目中，并使用此代码播放声音:

- (void)playSound:(NSString *)name withExtension:(NSString *)extension
{
    NSURL* soundUrl = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:name ofType:extension]]; 
    AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundUrl error:nil];
    audioPlayer.delegate = self;
    audioPlayer.volume = 1.0;
    [audioPlayer play];
}

我这样调用它:

[self playSound:@"wrong" withExtension:@"wav"];

但是我得到的声音为零。

更新的答案:

I've got the issue. It's with ARC and has nothing to do with prepareForPlay. Simply make a strong reference to it and it will work.

如下用户所述:Kinderchocolate :)

在代码中:

.h
~
@property (nonatomic, strong) AVAudioPlayer *player;


.m
~
@implementation
@synthesize _player = player;
