Answer 1

you’ll have to use MPMediaPickerControllerDelegate for this.

  //in your .h file include the MPMediaPickerControllerDelegate
  //in your .m file
  - (IBAction) showMediaFilesPressed : (id) sender 
  {
     MPMediaPickerController *picker =
     [[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeAnyAudio];

     picker.delegate                    = self;
     picker.allowsPickingMultipleItems  = NO;
     picker.prompt                      = NSLocalizedString(@"AddSongsPrompt", @"Prompt to user to choose some songs to play");



     [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleDefault animated:YES];

     [self presentModalViewController: picker animated: YES];
     [picker release];

 }

This will give you the all the media files listed on your device. And to play those files you may write the code for that in its delegate method.

  - (void)mediaPicker: (MPMediaPickerController *)mediaPicker didPickMediaItems:(MPMediaItemCollection *)mediaItemCollection
  {
          //play your file here
  }
