In my application using testflight, I see a crash below. I do not understand where and how this crash occurs. I have several UITableViewControllers in my application (about 10), so I'm not quite sure which code fragment to insert here. Any help would be really appreciated. I have already studied many questions, but I could not cover up the reason.
