Basically in app have a play button for audio file, want to add another UIButton Besides Play button so that whenever it is pressed it will repeat audio file for some number of times or may be infinite until it is pressed again to stop repetition of playing audio file. How can this be achieved.

Below is the code for play/pause toggle button

```
_playButton = [UIButton buttonWithType:UIButtonTypeCustom];
[_playButton addTarget:self action:@selector(playAction:) forControlEvents:UIControlEventTouchUpInside];
_playButton.frame = CGRectMake(80, 40, 25, 25);
[_playButton setImage:[UIImage imageNamed:@"1play.png"] forState:UIControlStateNormal];
[_playButton setImage:[UIImage imageNamed:@"audiopause.png"] forState:UIControlStateSelected];
UIBarButtonItem *play = [[UIBarButtonItem alloc] initWithCustomView:_playButton];

// Get the file path to the song to play.
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Theme"ofType:@"mp3"];

// Convert the file path to a URL.
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:filePath];

//Initialize the AVAudioPlayer.
player = [[AVAudioPlayer alloc]
          initWithContentsOfURL:fileURL error:nil];
player.delegate = self;

- (void)playAction:(id)sender
{
    if([player isPlaying])
    {
        [sender setImage:[UIImage imageNamed:@"1play.png"] forState:UIControlStateSelected];
        [player pause];
        //[timer invalidate];
        //timer = nil;
        //[self pauseTimer];
    }else{
        [sender setImage:[UIImage imageNamed:@"audiopause.png"] forState:UIControlStateNormal];
        [player play];
        slidertimer = [NSTimer timerWithTimeInterval:1.0 target:self selector:@selector(updateProgressBar:) userInfo:nil repeats:YES];
        [[NSRunLoop mainRunLoop] addTimer:slidertimer forMode:NSRunLoopCommonModes];
        timer = slidertimer;
    }
}

```
