MP3文件播放失敗的ios

Question

可能重複：
Sound stop playing

我真的很新的對iPhone應用程序開發。我想在我的應用程序中播放.mp3文件。 這是我試圖做的代碼片段。「dd.mp3」是在支持文件下的文件。但它不起作用。我做了什麼錯了嗎？

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

if(avPlayerObject) 
{ 
[avPlayerObject play]; 
} 

當我運行此代碼時我收到以下錯誤輸出。

Answer 1

我發佈了一個帶有指向另一個堆棧溢出鏈接的註釋你類似的，但這裏的問題是，將帶你一步一步的鏈接：

播放音頻在iOS應用：

Answer 2

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是音頻文件格式。

另外，將AVFoundation.framework添加到您的項目中。

添加到'.h'文件中。
