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

Just use this:

func removeBackButton(vc:UIViewController) {
        let button = UIButton.init(type: .custom)
        button.setImage(UIImage.init(named:""), for: .normal)
        let leftBarButton = UIBarButtonItem.init(customView: button)
        vc.navigationItem.leftBarButtonItem = leftBarButton
}

So call this method in viewDidLoad:

override func viewDidLoad() {
        super.viewDidLoad()
     removeBackButton(vc:self)
}
