Remove text from Back button keeping the icon

Question

I want to remove the text from the back button, but I want to keep the icon. I have tried

let backButton = UIBarButtonItem(title: \"\", style: UIBarButtonIt         


        

Answer 1

One alternative to override all ViewControllers for me was to extend UINavigationController and set the backBarButtonItem of the topViewController.

Swift 5 on Xcode 11.2.1:

extension UINavigationController {
    override open func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)

        let backButton = UIBarButtonItem(title: " ", style: .plain, target: nil, action: nil)
        self.topViewController?.navigationItem.backBarButtonItem = backButton
    }
}
