I had the same problem. For me, the app was crashing when I attempted to show a UIAlertView.

Turns out that all UI-related drawing functions need to be done on the UI thread (I already knew this, I guess I was just a little sloppy). Too bad the error message is cryptic.

Given that there are UIKit classes in the stacktrace you posted, I'm guessing this is your problem too.

this issue is quite simple to fix. Here just enter your code inbetween this code:

dispatch_async(dispatch_get_main_queue(), ^{
// Create and show your alert view here      
});
