One method for two UIButtons

Question

This rewind method is for rewind button as well as for play button.

-(void)rewind:(id)sender
{
    [timer invalidate]; 
    audioPlayer.currentTime = 0;

    MainViewController *viewController = [[MainViewController alloc] init];
    viewController.view.frame = CGRectMake(0, 0, 320, 480);
    [self.view addSubview:viewController.view];
    [self.view addSubview:toolbar];
    [viewController release];

    if([audioPlayer isPlaying])
    {
        [sender setImage:[UIImage imageNamed:@"Play Icon.png"] forState:UIControlStateSelected];
        [audioPlayer pause];
        [self pauseTimer];
        [self pauseLayer:self.view.layer];  
    }else{
        [sender setImage:[UIImage imageNamed:@"pause.png"] forState:UIControlStateNormal];
        [audioPlayer play];
        [self resumeTimer];
        [self resumeLayer:self.view.layer];
        if(isFirstTime == YES)
        {
            self.timer = [NSTimer scheduledTimerWithTimeInterval:11.0
                                                          target:self
                                                        selector:@selector(displayviewsAction:)
                                                        userInfo:nil
                                                         repeats:NO];
            isFirstTime = NO;
        }
    } 
}

Now in this method sender is rewind button and toggling of play/pause is happening on rewind button whereas i want this toggling on play button rather then sender which is rewind button. So i tried giving the name of the actual button on which i want toggling to happen and i defined that button as play button in my code and whose action method i have added in this rewind method.

That's how defined the play button

//Add Play Button
UIButton *playButton = [UIButton buttonWithType:UIButtonTypeCustom];
[playButton addTarget:self action:@selector(playpauseAction:) forControlEvents:UIControlEventTouchUpInside];
playButton.frame = CGRectMake(0, 0, 30, 30);
[playButton setImage:[UIImage imageNamed:@"Play Icon.png"] forState:UIControlStateNormal];
[playButton setImage:[UIImage imageNamed:@"pause.png"] forState:UIControlStateSelected];
UIBarButtonItem *play = [[UIBarButtonItem alloc] initWithCustomView:playButton];

and this is the method of play button which i added in the rewind button

-(void)playpauseAction:(id)sender 
{    
    if([audioPlayer isPlaying])
    {
        [sender setImage:[UIImage imageNamed:@"Play Icon.png"] forState:UIControlStateSelected];
        [audioPlayer pause];
        [self pauseTimer];
        [self pauseLayer:self.view.layer];
    }
    else
    {
        [sender setImage:[UIImage imageNamed:@"pause.png"] forState:UIControlStateNormal];
        [audioPlayer play];
        [self resumeTimer];
        [self resumeLayer:self.view.layer];

        if(isFirstTime == YES)
        {
            self.timer = [NSTimer scheduledTimerWithTimeInterval:11.0
                                                          target:self
                                                        selector:@selector(displayviewsAction:)
                                                        userInfo:nil
                                                         repeats:NO];
            isFirstTime = NO;
        }
    }
}

now problem i m facing at this time is that when i m clicking the rewind button toggling should happen on play button than rewind button.

But to fix this problem i simply replaced sender with playButton in the rewind method like this

[playButton setImage:[UIImage imageNamed:@"Play Icon.png"] forState:UIControlStateSelected];

but then i get warning message in red that use of undeclared identifier playButton.

How can i tell rewind method to do toggling on playButton rather then on rewind button.

Please help.

Thanks.
