AVAudioPlayer在iPhone 5中不起作用 [英] AVAudioPlayer is not working in iPhone 5

问题描述

我正在开发一个iPhone应用程序.在此应用程序中，我正在使用AVAudioPlayer播放音频.这是我播放声音的代码.

I am developing an iPhone application.In this app i am using AVAudioPlayer for playing audio. This is my code for playing the sound.

  NSString* resourcePath = [[NSBundle mainBundle] resourcePath];
    resourcePath = [resourcePath stringByAppendingString:@"/sound.mp3"];

    NSError* err;

    player_ = [[AVAudioPlayer alloc] initWithContentsOfURL:
               [NSURL fileURLWithPath:resourcePath] error:&err];

    if( err )
    {
    }
    else
    {
        [player_ prepareToPlay];

        [player_ play];

        int playingLoops = 0;

        player_.numberOfLoops = playingLoops;
    }

在除iPhone5以外的其他iPhone设备上都可以正常工作.虽然我在iPhone 5上运行该应用程序，但出现以下错误，然后应用程序崩溃了.

It is woking fine on iphone devices except iPhone5.While i run the app on iPhone 5 i get following error then app crashes.

推荐答案

我也遇到了相同的问题，并给出了相同的错误.当尝试解决此问题时，我注意到代码中没有问题.我们需要更新媒体播放器或安装Flash Player，一切正常.
