Run Timer for first time and resume timer for second time

Question

Declared variable in m file.

BOOL isFirstTime;

I want that if play button is pressed the very first time then it should toggle to pause button and check the function isFirstTime then it should start the timer and execute the displayviewsAction method and if the pause button is resumed to play back then it should check again the function isFirstTime or second time and if the hit is for the second time then it should resume timer.

-(void)playpauseAction:(id)sender {
if ([audioPlayer isPlaying]){         
   [sender setImage:[UIImage imageNamed:@"Play Icon.png"] forState:UIControlStateSelected];
   [audioPlayer pause];
   [self pauseTimer];
} else {
  [sender setImage:[UIImage imageNamed:@"pause.png"] forState:UIControlStateNormal];
  [audioPlayer play];
  [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(AfterOneSecondsFuction) userInfo:nil repeats:YES];
        }         
}
-(void)pauseTimer{
pauseStart = [[NSDate dateWithTimeIntervalSinceNow:0] retain];
previousFireDate = [[timer fireDate] retain];
[timer setFireDate:[NSDate distantFuture]];
}
 -(void)resumeTimer{
float pauseTime = -1*[pauseStart timeIntervalSinceNow];
[timer setFireDate:[previousFireDate initWithTimeInterval:pauseTime sinceDate:previousFireDate]];
[pauseStart release];
[previousFireDate release];    
}
-(void)AfterOneSecondsFuction
{
if(!isFirstTime)
{
 isFirstTime=YES;
 return;
 self.timer = [NSTimer scheduledTimerWithTimeInterval:11.0
                                                  target:self
                                                selector:@selector(displayviewsAction:)
                                                userInfo:nil
                                                repeats:NO];

} else if (!isFirstTime){
  isFirstTime=NO;
  return;
  [self resumeTimer]; 

     }
}    

- (void)displayviewsAction:(id)sender
{  
  First *firstController = [[First alloc] init];
firstController.view.frame = CGRectMake(0, 0, 320, 480);
CATransition *transitionAnimation = [CATransition animation];   
[transitionAnimation setDuration:1];
[transitionAnimation setType:kCATransitionFade];
[transitionAnimation setTimingFunction:[CAMediaTimingFunction     functionWithName:kCAMediaTimingFunctionEaseIn]];
[self.view.layer addAnimation:transitionAnimation forKey:kCATransitionFade];
[self.view addSubview:firstController.view];
[self.view addSubview:toolbar];
[firstController release];   
}

-(void)Second 
{
 Second *secondController = [[Second alloc] init];
secondController.view.frame = CGRectMake(0, 0, 320, 480);
CATransition *transitionAnimation = [CATransition animation];
[transitionAnimation setDuration:1];
[transitionAnimation setType:kCATransitionReveal];
[transitionAnimation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn]];
[self.view.layer addAnimation:transitionAnimation forKey:kCATransitionReveal];
[self.view addSubview:secondController.view]; 
[self.view addSubview:toolbar];
[secondController release];
self.timer = [NSTimer scheduledTimerWithTimeInterval:27 target:self selector:@selector(Third) userInfo:nil repeats:NO];
 }

Looks like when play is pressed first it is only toggling to pause button not checking the function isFirstTime or not and not starting the timer and executing displayviewsaction.

If anyone can tell why it is not happening and what im doing wrong.

Thanks for help.

BOOL isFirstTime

//Somewhere where the object is set up, isFirstTime should be set to YES


- (void)playpauseAction:(id)sender {

//When the button is pressed

if(isFirstTime) {

//Load the sound file
//Start playing the sound
//Start view controller timers
//Change the button image to paused
isFirstTime = FALSE;

}

else {

//The button has already been pressed

if ([audioPlayer isPlaying]) {

//If the sound is playing

//Stop playing the sound
//Stop view controller timers
//Change the button image to playing

}

else {

//Resume playing the sound
//Start view controller timers
//Change the button image to paused

}

}
