backBarButtonItem in iOS (Swift)

Question

var backButton: UIBarButtonItem = UIBarButtonItem(title: "CUSTOM", style: UIBarButtonItemStyle.Bordered, target: self, action: nil)
    newNavigationItem.backBarButtonItem = backButton

Where is newNavigationItem: UINavigationItem

I want custom back title. It shows "Back" text or "Title of last view". So it does not work. Why?

The method that Yogesh Suthar said will replace the whole back button, so you will not have the default left arrow sign! I suggest to use this code:

navigationController?.navigationBar.topItem?.backBarButtonItem = backButton

Do you put this in the parent view controller? – hungrxyz Oct 09 '15 at 20:08
Yeah. You can do this anywhere that you have access to the navigationViewcontroller. – Majid Oct 10 '15 at 02:44
This should be the accepted answer. Setting the leftBarButtonItem is a workaround. In swift 2 I used this in the viewDidLoad of the view controller pushing to the one I wanted to change the back title on: `navigationController?.navigationBar.topItem?.backBarButtonItem = UIBarButtonItem(title: "Back", style: .Plain, target: nil, action: nil)` – earnshavian Nov 04 '15 at 18:29
@Majid +1 for best answer. Now I can also use this solution. :) – Yogesh Suthar Dec 31 '16 at 12:20

@MaximDroy Why aren't you setting the title property instead? No need to create a whole new UIBarButtonItem. See: http://stackoverflow.com/questions/20282760/back-text-displayed-in-ios7-navigationbar-when-view-title-is-long – klcjr89 Jul 12 '14 at 14:24

@MaximDroy Sorry for late reply. For your first question about "Action", you need to create a custom function and you need to pop VC, you can use this code `self.navigationController.popViewControllerAnimated(true)`. – Yogesh Suthar Jul 12 '14 at 14:47
Setting leftBarButtonItem is a workaround - instead set the backBarButtonItem to a custom UIBarButtonItem in the viewDidLoad of the view controller pushing to the one you want to change as suggested by @Majid below http://stackoverflow.com/a/30250603/169902 – earnshavian Nov 04 '15 at 18:32
Using this solution will disable swipe back action. – Arijan Mar 04 '22 at 20:09

override func viewDidLoad() {
 super.viewDidLoad()
  let newBackButton = UIBarButtonItem(title: "Back",
         style: UIBarButtonItemStyle.Plain, target: self, action: "backAction")
    navigationController?.navigationBar.topItem?.backBarButtonItem = newBackButton

}

func backAction() -> Void {
    self.navigationController?.popViewControllerAnimated(true)
}

Setting custom UIBarButtonItem as backBarButtonItem in my case had some padding from left. After close inspection it showed default image from Back Button was visible.

What worked for me:

navigationController?.navigationBar.backIndicatorImage = UIImage()
navigationController?.navigationBar.backIndicatorTransitionMaskImage = UIImage()
navigationController?.navigationBar.topItem?.backBarButtonItem = UIBarButtonItem(image: UIImage(named: "backIcon"), style: .plain, target: self, action: nil)

With this logic swipe back is working normally and also click on back button pops viewcontroller.
