How to remove all navigationbar back button title

Question

When I push a UIViewController, it has some title in back button at new UIViewController, if the title has a lot of text, It does not look good in

Answer 1

You could create a subclass for all UIViewControllers you want this behavior for, and in the subclass's viewDidLoad:

override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationItem.backBarButtonItem = UIBarButtonItem(
        title: "", style: .plain, target: nil, action: nil)
}

This way, you can choose which controllers you want the behavior for, without duplicating code. I prefer my controllers to just say "Back", rather than the title of the previous controller, so I set that title here.
