I have a random-looking crash related to UIKit and I can't seem to figure out what is wrong.

Does anyone see a familiar pattern here or do you think this might be a random OS-related crash? Is there a way to find out which Buttons or UI-elements were involved here?

  • I also tend to experience 'random' crashes especially using UIAlertView. Do you have any code to share? –  Sep 09 '12 at 10:20
