サウンドの再生が停止する

iPhoneアプリ開発初心者です。アプリで .mp3 ファイルを再生したい。これが私がやろうとしたコードスニペットです.「dd.mp3」は、サポートファイルの下にあるファイルです。しかし、それは機能していません。私が何か間違ったことはありますか？

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

if(avPlayerObject)
{
 [avPlayerObject play];
}

このコードを実行すると、次のエラー出力が表示されます。

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 は音声ファイル形式です。

また、AVFoundation.framework をプロジェクトに追加します。

を「.h」ファイルに追加します。
