Understanding navigationItem property
Hey,
Every instance of UIViewController has a property named navigationItem.
It is used to represent the view controller when it is pushed onto a navigation bar.
Is this what UINavigationController uses as "The Back Button" when pushing views into the stack?
One more thing,
At any given view, the back button showed by the navigation controller doesn't represent the navigationItem of the showed controller, it is the navigationItem of the previous showed controller, right?
Thanks for help and time.
