You need to create a cgrect and apply that to you view/imageview

here is a code snippet

CGRect previousFrame = view.frame;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5f];
previousFrame.size.width = 100;
previousFrame.size.height = 100;
view.frame = previousFrame;
[UIView commitAnimations];

paste this code on IBAction of your button. Change the code as you want. this is just for understanding the concept.
