Making an animation to expand and shrink an UIView

Question

I want to create an animation that will resize an UIView and its contents by a factor. Basically, I want to make an animation that first expands the view then shrinks it bac

Answer 1

Here is a smaller approach that also loops:

[UIView animateWithDuration:1
                      delay:0
                    options:UIViewKeyframeAnimationOptionAutoreverse | UIViewKeyframeAnimationOptionRepeat
                 animations:^{
                     yourView.transform = CGAffineTransformMakeScale(1.5, 1.5);
                 }
                 completion:nil];

The option UIViewKeyframeAnimationOptionRepeat is what makes it loop, if you don't want it to keep "breathing". The animation block acts as the "inhale" and the UIViewKeyframeAnimationOptionAutoreverse option automatically plays the "exhale" animation.
