How to change text on a back button

Question

By default the back button uses as a text on it a title of a viewcontroller. Can I change text on the back button without changing a title of a view controller? I need this

Answer 1

If you want not only to change the text of the Back button and remain the original left-arrow shape, but also to do something when user clicks the Back button, I recommend you to have a look around my "CustomNavigationController".
