I have a very strange issue. I have no device specific code. I'm not even using autolayout since I'm targeting back to iOS 4.3. So I tested on my iPhone 4S, and everything was fine. Sent it out for beta testing, and iPhone 5 users reported that one of the two buttons on my sign in view (the sign in button, a relatively important one), didn't work. It's not even detecting a touch down (not changing colors). I fired up the simulator, and in the iPhone 5 simulator, NEITHER of the buttons worked.
Anyone have any idea what's going on here? I'm happy to share any code you think might be relevant, but I don't even know where to start, as there is no device specific code, and it works perfectly fine on the 4S, and behaves differently on the 5 and still differently on the 5 simulator.
EDIT: Turns out a view was overlapping the buttons due to autosizing. Figured this out by changing the Size in the .xib to retina 4 inch.
