I am trying to automatically expand a UIButton width to the width of an interface upon orientation change.
Does anyone have working code for this? I have tried using AutoResizing mask, but perhaps I'm not using the correct one.
What is the correct way to auto expand a UIButton to the width of an interface on orientation change

using constraints or autolayout. – hcarrasko Apr 09 '14 at 20:29

You could also override layoutSubviews in the ViewController, to position and resize manually (and if you need pixel precision). Though auto-layout is easier I'd say. – Wolfgang Schreurs Apr 09 '14 at 20:44

There's multiple ways of doing this.
In your view controller sub class overrride -willAnimateRotationToInterfaceOrientation:duration: or -willRotateToInterfaceOrientation:duration:
You could also override -viewWillLayoutSubviews and then adjust the frame depending on the orientation by querying self.interfaceOrientation.
And change the size of the button in that method, either by adjusting the constraints or changing the frame of the button.
