How to animate the width and height of a UIView in Xcode?

Question

I have this subview I want to add to my main view, but make it expand from the origin. I read some of the Apple documentation but I don\'t understand where I am making mistake.

Answer 1

If your viewcontrollers viewWillLayoutSubviews (or such) sets the "initial" frame of yourView, then that apparently gets called during the animation cycle, and would therefore reset the frame set by the animation.
