Resume Updating views after time is invalidated

Time is invalidated to pause the views from updating because pause button was hit to pause the audio file.

Next step is when user hits pause button again to resume audiofile, views should also start updating.

-(void)playpauseAction:(id)sender 

{



if  



  ([audioPlayer isPlaying]){



 [sender setImage:[UIImage imageNamed:@"play.png"] forState:UIControlStateSelected];



  [audioPlayer pause];



   [timer invalidate];



  } else {



 [sender setImage:[UIImage imageNamed:@"pause.png"] forState:UIControlStateNormal];



      [audioPlayer play];



      self.timer = [NSTimer scheduledTimerWithTimeInterval:11 target:self selector:@selector(displayviewsAction:) userInfo:nil repeats:NO];



  }  



}



- (void)displayviewsAction:(id)sender

{

FirstViewController *viewController = [[FirstViewController alloc] init];



viewController.view.frame = CGRectMake(0, 0, 320, 480);



[self.view addSubview:viewController.view];



[self.view addSubview:toolbar];



self.timer = [NSTimer scheduledTimerWithTimeInterval:23 target:self selector:@selector(secondViewController) userInfo:nil repeats:NO];



[viewController release];



}



-(void)secondViewController {

SecondViewController *secondController = [[SecondViewController alloc] init];



secondController.view.frame = CGRectMake(0, 0, 320, 480);



[self.view addSubview:secondController.view]; 



[self.view addSubview:toolbar];



self.timer = [NSTimer scheduledTimerWithTimeInterval:27 target:self selector:@selector(ThirdviewController) userInfo:nil repeats:NO];



[secondController release];

}

It goes like this for 20 views. As per the application logic user can hit pause on any view to pause the audio file and pluse it will also pause views from updating. When user will hit pause again to resume audio file it should start updating views from that point onwards.

Anyone knows how to achieve this in coding.

Appreciate help.
