Override IBOutlet properties from super class?

Don't try to recreate the variables in the subclass; the IBOutlet variables still exist. You can still connect them inside of Interface Builder in a number of ways.

1. Utilites (right panel) -> Connection Inspector - drag from the list of IBOutlets.
2. Document Outline (left panel) - drag from MyDetailViewController
3. Drag from the yellow circle when you have the UIViewController selected in Interface Builder

Note: All UIViewController subclasses inherit an IBOutlet named view; this property already exists in Interface Builder even though you can't click + drag to connect it.
