MP3文件播放失败的ios

-2

可能重复：
Sound stop playing MP3文件播放失败的ios

我真的很新的对iPhone应用程序开发。我想在我的应用程序中播放.mp3文件。这是我试图做的代码片段。“dd.mp3”是在支持文件下的文件。但它不起作用。我做了什么错了吗？

NSError *error=nil; 
NSURL *audioURL =[[NSBundle mainBundle] URLForResource:@"dd" withExtension:@"mp3"]; 
AVAudioPlayer *avPlayerObject = [[AVAudioPlayer alloc] initWithContentsOfURL:audioURL error:&error]; 

if(avPlayerObject) 
{ 
[avPlayerObject play]; 
}

当我运行此代码时我收到以下错误输出。

@Intrus：我认为“NSSound”适用于mac开发。不是iPhone – sashmarsh 2012-08-08 05:49:28

我发布了一个带有指向另一个堆栈溢出链接的注释你类似的，但这里的问题是，将带你一步一步的链接：

谢谢Intrus :)问题解决了 – sashmarsh 2012-08-15 08:29:39

NSString *path = [[NSBundle mainBundle] pathForResource:@"sound" ofType:@"caf"]; 
self.audioPlayer =[[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL fileURLWithPath:path] error:nil]; 
[self.audioPlayer setDelegate:self]; 
[self.audioPlayer prepareToPlay]; 
[self.audioPlayer play];

CAF是音频文件格式。

另外，将AVFoundation.framework添加到您的项目中。

添加到'.h'文件中。
