popViewController to a UIViewController initialized with a UIStoryboardSegue
===

I have a list controller that fires a `performSegueWithIdentifier` to load a detailViewController of the item that was selected. To initialize the detailViewController I set a property on it in the `prepareForSegue` that gets called before the detailView is shown. This all works great.

However...  
From the detail view I navigate to a controller that does some memory intensive actions and my detailViewController ends up being unloaded and `viewDidUnload` gets called.

Now the user presses the back button in the title bar causing `popViewController` to fire. When my `viewDidLoad` method for the detailViewController executes again, I haven't had the opportunity to set the appropriate property before it's displayed. So at this point none of my controls display proper/any information.

What is the best way to re-initialize the property on my detailViewController once it has been deallocated and the user navigates back to it? I have thought of setting the "selectedItem" on my AppDelegate to use in this situation but that seems like a hack.

Thanks in advance!
