UIButtons not working on certain devices

Question

I've set up a view and constraints using the wAny hAny layout in Xcode 6:

When I run the app on a iPhone 5s and iPhone 6 the UI Elements are all visible but on the 5s the answer and the back buttons do not work - they do nothing.

On the iPhone 6 all the buttons work.

Here's the code for the `back' button:

- (IBAction)backFromDivision:(id)sender {
[self dismissViewControllerAnimated:YES completion:nil];
}

The answer code is a bit longer and I won't post it unless necessary.

Does this have something to do with the constraints or should I be looking for answers elsewhere?

Answer 1

Well,

I clicked on "Resolve Auto Layout Issues" - "Reset to suggested constraints" (third from the left):

and that "solved" my problem. Everything is working on all devices. It seems to have removed some constraints that I put in place.

I'm going to have to learn more about why this worked.

Answer 2

I've had a similar issue before. It was the constraints that were the issue and the fact that the button was not in the view's bounds.
