Hello Gustavo.
This sounds like a perfect job for Core Animation.
With Core Animation, you can apply the animation to the UIImageView's layer.
Core Animation allows for animations to run once and stop automatically, repeat
a specific number of times, or repeat indefinitely until you tell it to stop.
I do something very similar in one of my projects. Here is how you set up the
rotation animation (do this to each of your 4 views that you want to rotate):
CABasicAnimation *rotationAnimation = [CABasicAnimation
animationWithKeyPath:@"transform.rotation"];
rotationAnimation.duration = 1.0;
rotationAnimation.fromValue = [NSNumber numberWithFloat:0.0];
rotationAnimation.toValue = [NSNumber numberWithFloat:2.0*M_PI];
rotationAnimation.repeatCount = HUGE_VALF;
[flashImageView.layer addAnimation:rotationAnimation
forKey:@"RotatingFlash"];
When you want the animation to stop do this:
[flashImageView.layer removeAnimationForKey:@"RotatingFlash"];
