If you're seeing that then it's highly likely your program has terminated due to an uncaught exception. Take a look at this question to see how to set a breakpoint in objc_exception_throw which will then help as you'll be dropped right into the code that's causing the exception to be thrown.

This is the way to go. NSZombie is also helpful but not directly the issue behind your specific question. – Dancreek Jan 13 '12 at 15:37
Indeed. It's getting to be the defacto thing people say when people have a crash - "Turn on zombies". Sure, in my opinion you should always (in general) dev with it on, but it's not likely going to be of help here. – mattjgalloway Jan 13 '12 at 15:42

Did you enable Zombies? To do it do the following:

1) Click on your app name(next to the Run and Stop buttons on top)

2) Click "Edit Scheme..."

3) In "Memory Management" put a tick on "Enable Zombie Objects"

Or you can get there by clicking "Product" --> "Edit Scheme..."

Hope it helps
