Back Bar Button Segue hides Toolbar

Question

I am using a Show segue in my application. Whenever I segue to another screen and press the back bar button, my navigationController.toolbar disappears.

I tried to get rid of it with

        navigationController?.toolbar.hidden = false

in my viewDidLoad(). It doesn't work though. Any ideas?

You wanna hide the navigationBar when pressing the back button, or the navigationBar is disappearing and you want it to not disappear? — Diogo Antunes, May 15 '16 at 15:37
@DiogoAntunes I want it to appear, rather than hide. It hides automatically. — JVS, May 15 '16 at 15:51

Thank you. It is important to put it in ViewWillAppear() – JVS May 15 '16 at 15:53

Please add the code in the viewWillAppear() and it should solve the problem you are facing.

 override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    navigationController?.toolbarHidden = false

}

Remember that viewDidLoad() fires only once during the life cycle of a view controller and in your case , it is in the navigation stack which means it has been already used for that view controller and now when you press back button, it does not work again.

Thanks. Also for the brilliant explanation. – JVS May 15 '16 at 15:53 — JVS, May 15 '16 at 15:53
