action sequence (objective C) iPhone

I'm having a issue figuring out how to do make sequential actions occur.

Broken down to its simplest form what I'm trying to do is make image1 grow 25% larger and only upon completion of this action will a sound play.

I can make the image grow, I can make the sound play, no problem, but I cannot figure out how to make the sound play ONLY after the image has grown it's 25 percent.

Any help would be great.

Thanks.

Are you are using an animation to resize the image/view? If so you 

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.0f];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(resizeFinished:finished:context:)];
// Resize the view/image here
[UIView commitAnimations];

and then in the selector you can play the sound

- (void)resizeFinished:(NSString *)animationID finished:(BOOL)finished context:(void *)context;
{
    // Play the sound here
}

You can also implement the callback delegate

- (void)animationDidStop:(CAAnimation *)theAnimation finished:(BOOL)flag

If you use core animation, you can run your continuation logic in a completion block (iOS 4). Or you can register a callback on setAnimationDidStopSelector. Take a look here for details.
