How to set back button text in iOS navigation controller?

How do you remove the back button text.

Current back button:

< Back

Desired back button:

< AnythingElse

None of these have worked:

self.navigationItem.backBarButtonItem?.title = "Back"
self.backItem?.title = ""
self.navigationController?.navigationBar.backItem?.title = ""
self.navigationItem.backBarButtonItem?.title = ""
self.navigationController?.navigationItem.backBarButtonItem?.title="Back"
self.navigationController?.navigationBar.backItem?.title = ""
self.navigationController?.navigationItem.backBarButtonItem?.title

Following code can be added to a view controller from where you are pushing view controller in which you want to change back button text

Swift 5

self.navigationItem.backBarButtonItem = UIBarButtonItem(title: "", style: .plain, target: self, action: nil)

For example:-

ViewController1
ViewController2

Assume we want to update back title of viewcontroller2 and we are pushing viewcontroller2 from viewcontroller1.

then you can use following code:-

let vc2 = storyboard.instantiateViewController(withIdentifier: "ViewController2")
self.navigationItem.backBarButtonItem = UIBarButtonItem(title:  "your custom back button title", style: .plain, target: self, action: nil)
self.navigationController?.pushViewController(vc2, animated: true)

Solution checked and work in Swift 5

Below I put few solutions for different cases:

1. Remove text from back button

The best solution to remove text from back button is to add in viewDidLoad():

navigationItem.backBarButtonItem = UIBarButtonItem()

2. Set own text on back button

In case you want to set your own title, do it by setting title of backButton:

let backButton = UIBarButtonItem()
backButton.title = "My Title"
navigationItem.backBarButtonItem = backItem

3. Empty back button on all VC

If you want to create common style in entire app - to have just arrow back without text, create base VC for all your View Controllers:

class BaseViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()

        navigationItem.backBarButtonItem = UIBarButtonItem()
    }
}

Solution presented above let you customize back button in the future if you want to make some exception later, by adding additional variable and overriding it in specific ViewController, f.ex:

class BaseViewController: UIViewController {

    var customBackButtonTitle: String?

    override func viewDidLoad() {
        super.viewDidLoad()

        var backButton = UIBarButtonItem()
        if let text = customBackButtonTitle {
            backButton.title = text
        }
        navigationItem.backBarButtonItem = backButton
    }
}

You can put this 3 line of code in the ViewController you want to change the back button title.

In your override func viewDidLoad() {}.

let backButton = UIBarButtonItem()
backButton.title = "My Back Button Title"
self.navigationController?.navigationBar.topItem?.backBarButtonItem = backButton

GOTCHA: If you are having trouble with any of the many-starred suggestions, ensure that you are registering your UITableViewCells in viewDidLoad(), not from init()

There are two ways.

1.In the previousViewController.viewDidLoad()

let backBarBtnItem = UIBarButtonItem()
backBarBtnItem.title = "back"
navigationItem.backBarButtonItem = backBarBtnItem

2.In the currentViewController.viewDidAppear()

let backBarBtnItem = UIBarButtonItem()
backBarBtnItem.title = "back"      
navigationController?.navigationBar.backItem?.backBarButtonItem = backBarBtnItem

Reason : the backButton comes from navigationBar.backItem.backBarButtonItem,so the first way is obvious.In currentViewController.viewDidLoad(),we can't obtain the reference of backItem,because in viewDidAppear(),the navigationBar pushed navigationView on its stack.so we can make changes to the backItem in currentViewController.viewDidAppear()

The back button belongs to the previous view controller, not the one currently presented on screen.
To modify the back button you should update it before pushing, on the view controller that initiated the segue:

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    let backItem = UIBarButtonItem()
    backItem.title = "Something Else"
    navigationItem.backBarButtonItem = backItem // This will show in the next view controller being pushed
}

Swift 3, 4 & 5:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    let backItem = UIBarButtonItem()
    backItem.title = "Something Else"
    navigationItem.backBarButtonItem = backItem // This will show in the next view controller being pushed
}

// in your viewDidLoad or viewWillAppear
navigationItem.backBarButtonItem = UIBarButtonItem(
    title: "Something Else", style: .plain, target: nil, action: nil)

This works for Swift 5:

self.navigationItem.backBarButtonItem?.title = ""

Please note it will be effective for the next pushed view controller not the current one on the display, that's why it's very confusing!

Also, check the storyboard and select the navigation item of the previous view controller then type something in the Back Button (Inspector).

Swift 4.2

If you want to change the navigation bar back button item text, put this in viewDidLoad of the controller BEFORE the one where the back button shows, NOT on the view controller where the back button is visible.

 let backButton = UIBarButtonItem()
 backButton.title = "New Back Button Text"
 self.navigationController?.navigationBar.topItem?.backBarButtonItem = backButton

If you want to change the current navigation bar title text use the code below (note that this becomes the default back text for the NEXT view pushed onto the navigation controller, but this default back text can be overridden by the code above)

 self.title = "Navigation Bar Title"

The back button belongs to the previous view controller, not the one currently presented on screen. To modify the back button you should update it before pushing, add viewdidload :

While the previous saying to prepare for segue is correct and its true the back button belongs to the previous VC, its just adding a bunch more unnecessary code.

The best thing to do is set the title of the current VC in viewDidLoad and it'll automatically set the back button title correctly on the next VC. This line worked for me

navigationController?.navigationBar.topItem?.title = "Title"

although these answers fix the problem but this could be some useful

class MainNavigatioController: UINavigationController {

    override func pushViewController(_ viewController: UIViewController, animated: Bool) {
        // first
        let backItem = UIBarButtonItem()
        backItem.title = "رجوع"
        self.viewControllers.last?.navigationItem.backBarButtonItem = backItem
        // then
        super.pushViewController(viewController, animated: animated)

    }

}

In my case the solution was to clear the navigation item of the Master View Controller before move to the Child View Controller. And set it again if it is shown again

MasterController

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    navigationItem.title = "Master Title"
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    navigationItem.title = ""
}

And this is how I push a UIViewController and clear the back bar button item in the child controller:

MasterController

let childController = ChildController(collectionViewLayout: UICollectionViewFlowLayout())
childController.navigationItem.backBarButtonItem?.title = ""
navigationController?.pushViewController(childController, animated: true)

This should work:

override func viewDidLoad() {
    super.viewDidLoad()

    var button = UIBarButtonItem(title: "YourTitle", style: UIBarButtonItemStyle.Bordered, target: self, action: "goBack")
    self.navigationItem.backBarButtonItem = button

}

func goBack()
{
    self.navigationController?.popViewControllerAnimated(true)
}

Although it is not recommended since this actually replaces the backButton and it also removed the back arrow and the swipe gesture.

Swift 4 - Configure the back button before pushing any view controllers

// if you want to remove the text
navigationItem.backBarButtonItem = UIBarButtonItem()

// if you want to modify the text to "back"
navigationItem.backBarButtonItem = UIBarButtonItem(title: "back", style: .plain, target: nil, action: nil)

You can just modify the NavigationItem in the storyboard

In the Back Button add a space and press Enter.

Note: Do this in the previous VC.

If you are pushing a view controller from page view controller page, you cannot update the navigation controller's back button title. To solve this create a delegate back to your parent view controller (you may also be able to traverse the view controller hierarchy back up to the parent).

Furthermore, Back buttons have a character limit. If you exceed that character limit, the system will default to "Back". It will not truncate for you. For example:

backItem.title = "Birthdays/Anniversaries" // Get's converted to "Back".
backItem.title = "Birthdays/Anniversa…" // Fits and shows as is.

If you are using xib file for view controller then do this in your view controller class.

class AboutUsViewController: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()
    edgesForExtendedLayout = []
    setUpNavBar()
}

func setUpNavBar(){
    //For title in navigation bar
    self.navigationController?.view.backgroundColor = UIColor.white
    self.navigationController?.view.tintColor = UIColor.orange
    self.navigationItem.title = "About Us"

    //For back button in navigation bar
    let backButton = UIBarButtonItem()
    backButton.title = "Back"
    self.navigationController?.navigationBar.topItem?.backBarButtonItem = backButton
}

}

The result will be:

Try this... it will work ....

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    self.title = ""
}

The above code will hide the text and show only the back arrow on navigation bar.

I do not know where you have used your methods that you put on your question but I could get the desired result if I use, on my ViewController class (in which I want to change the back button), on viewDidLoad() function, the following line:

self.navigationController?.navigationBar.backItem?.title = "Anything Else"

The result will be:

Before

After

Back-button text is taken from parent view-controller's navigation item title. So whatever you set on previous view-controller's navigation item title, will be shown on current view controller's back button text. You can just put "" as navigation item title in parent view-controller's viewWillAppear method.

self.navigationItem.title = ""

Another way is to put

self.navigationController?.navigationBar.topItem?.title = ""

in current view controller's viewWillAppear method. This one will cause some other problem if navigation stack is too nested.
