Trying to find the source of this EXC_BAD_ACCESS in my iOS App. I get the following on the console:

[_UILayoutGuide isDescendantOfView:]: message sent to deallocated instance 0x7fd14037d0e0

And have used Zombies to try to track this down:

I can't find the source of the problem. Double clicking on any of the stack traces in Zombies doesn't lead to any of my code.

Hope you can help - before I bang my head too hard off the wall!

-Thanks

I finally found the answer - the problem was a constraint in the Storyboard.

The constraint was not "installed", but I found that by deleting UI elements one by one I could track down the problem constraint. No apparent reason why it would cause a crash like this, but deleting it has fixed the issue.
