Don't expect anyone to help you find anything from a crash report, zero code, zero explanations of the context, and zero explanations of what you tried. – zneak
I agree with zneak. Provide some code and a description. – Dimitris Tavlikos
I think you just threw up on my browser. – jonathanpeppers
I dont know what else to say. Any time I touch on an event on a table it blows up with this stack trace. Even when I dont have a delegate attached. – Mardo

I'm willing to bet that the problem is that you have a UIViewController or a button, that is defined within the scope of a method, like your Main, not realizing that it will present before being garbage collected and then, as soon as you do anything, it crashes like this.

I've had it happen a couple of times.
