Foundation includes a feature called "zombie objects" that is designed to help track stuff like this. With zombies enabled, hitting a deallocated object will give you a chance to see what's going on. Here's how to enable it:

  • Navigate to the Scheme editor. You can get here a variety of ways, but my favorite is to option-click the Run button.
  • Make sure the Run action is selected in the sidebar and then select the Diagnostics tab
  • Select "Enable Zombie Objects" (fourth from the top)

Then build and run and exercise the code that crashes. When it stops in the debugger, you'll see something in the console like "message sent to deallocated object 0x00..." Let me know what it says, and I'll try to help figure out what's going on.

Forget the crash details for now and show some code:


Are you calling 

[self.navigationController popToRootViewControllerAnimated:YES]
?


...and then maybe 

[self.navigationController pushViewController:someOtherViewController]
?
