The \"back button\" of a UINavigationController by default shows the title of the last view in the stack. Is there a way to have custom text in the back button
rein's answer works well.
Note that if you push more than one view controller, the changed back button title will appear for each of them, which may not be what you want.
In that case, you'll need to create the custom UIBarButtonItem each time you push a view controller.
Also, make sure you do it before pushing the view controller, otherwise you will get a screen hiccup as the title changes.
