MP3 file from server is not playing with AVAudioPlayer in iOS7

Question

Here is my code, In this first I am calling mp3 url for downloading the audio data. then I am saving that data in local directory, After that I am playing audio from local file path but its not working AVAudioPlayer throwing error. I have tried some other ways also but no one work for me. On simulator same code is working fine. And the audio url is playing like a charm in browser.

 NSURL *urlll=[NSURL URLWithString:@"www.xyz.audio.mp3"];

[NSURLConnection sendAsynchronousRequest:[NSURLRequest requestWithURL:urlll] queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *responce,NSData* data,NSError * error) {
        if (error == nil)
        {
            indicator.hidden=YES;
            [indicator stopAnimating];

            if (data)
            {
               NSString *docDirPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
                NSString *filePath = [NSString stringWithFormat:@"%@/%@.mp3", docDirPath , @"Audio"];
                [data writeToFile:filePath atomically:YES];

              NSURL *fileURL = [NSURL fileURLWithPath:filePath];
                AudioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:&error];

                AudioPlayer.delegate=self;
                [AudioPlayer prepareToPlay];
                if (AudioPlayer == nil) {
                    NSLog(@"AudioPlayer did not load properly: %@", [error description]);
                } else {
                    [AudioPlayer play];

                }
           }
      }
}];

But I am getting these kind of errors : E rror Domain=NSOSStatusErrorDomain Code=1685348671 "The operation couldn't be completed. (OSStatus error 1685348671.)

Please Help me :( .

In your code you save the audio to NSString *filePath but you initiate with fileURL . Could it be that you actually wanted to do this:

AudioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL URLWithString:filePath] error:&error];

If not then you should know that the error is reporting to you a kAudioFileInvalidFileError . Which means the file is malformed. You could try other formats like . caf or . aifc or aiff .

--edit--

Make sure the AVAudioPlayer is a property in .m or .h file, so the memory allocation lasts after leaving the method:

@property (nonatomic,strong) AVAudioPlayer *AudioPlayer;

(side note: properties should start with lowercase -> audioPlayer )
