I already read multiple posts regarding this, but couldn't get it working.

Custom rightBarButtonItem disappearing
RightBarButtonItem disappears when view appears again
I have a ViewController-A embedded in a UINavigationController. The navigation bar of the controller contains a rightBarButtonItem. Code for adding rightBarButtonItem:
let searchButton = UIBarButtonItem(image: UIImage(named: "HomeSearch"), style: .plain, target: self, action: #selector(navigateToSearchScreen))
self.navigationItem.rightBarButtonItem = searchButton
When another ViewController-B is pushed in the navigation stack and popped back, the rightBarButtonItem disappears from the navigation bar.
I think in nextViewcontroller you hide the navigation right bar so When you pop then nav button will not display So You have to add right bar button in viewWillAppear:
override func viewWillAppear(_ animated: Bool) {
let searchButton = UIBarButtonItem(image: UIImage(named: "HomeSearch"), style: .plain, target: self, action: #selector(navigateToSearchScreen))
self.navigationItem.rightBarButtonItem = searchButton
}
I am trying to code without using Storyboard or Interface Builder in my project. So, in the need of create a side menu for my app, I want to create a Navigation Bar to give the chance to open the menu by tapping on the left button of my navigation Bar.
This is what I have tried with no success:
override func viewDidLoad() {
super.viewDidLoad()
centerViewController = ViewController()
centerViewController.delegate = self
centerNavigationController = UINavigationController(rootViewController: centerViewController)
let menuButton: UIBarButtonItem = UIBarButtonItem(title: "TMDB", style: .plain, target: centerViewController, action: Selector(("toggleLeftButton")))
centerNavigationController.navigationItem.leftBarButtonItem = menuButton
view.addSubview(centerNavigationController.view)
addChildViewController(centerNavigationController)
centerNavigationController.didMove(toParentViewController: self)
}
My Navigation Bar is not showing any button nor title.
I know that is no longer necessary but still. His lessons are helpfull https://www.youtube.com/watch?v=zS-CCd4xmRY
Solved
The problem was where I was writting the code. It must be instantiated inside the viewController where the NavigationController belongs.
I mean, inside the centerViewController not in his parent as I was doing.
This lines of code:
let menuButton: UIBarButtonItem = UIBarButtonItem(title: "TMDB", style: .plain, target: self, action: Selector(("toggleLeftButton")))
self.navigationItem.leftBarButtonItem = menuButton
Inside the controller ViewController.
EDIT
Reference:
Adding UIBarButtonItem to UINav..Controller
How can I change back button place to right bar button of embedded navigation and change the the icon from < to >?
My suggestion is:
Hide back button:
navigationItem.hidesBackButton = YES
Add a right button with an image arrow:
let backButton = UIBarButtonItem(title: ">", style: .Plain, target: self, action: #selector(backTapped))
navigationItem.rightBarButtonItem = backButton
the action of backTapped will pop the view controller from the navigation controller stack.
Let me know in the comments if this approach can resolve your problem.
I use :
let newView = sabtEnsheabViewController(nibName: "sabtEnsheabViewController", bundle: nil)
self.navigationController?.pushViewController(newView, animated: false)
but it show back button to another view
use this :
let newView = EnsheabSabteNamViewController(nibName: "EnsheabSabteNamViewController", bundle: nil)
self.presentViewController(newView, animated: false, completion: nil)
it doesn't show navigationBar anymore
I use this way for change back button position.
//put this code in viewDidLoad()
navigationItem.hidesBackButton = true
navigationItem.rightBarButtonItem = UIBarButtonItem(title: " > ", style: .done,target: self, action: #selector(addTapped))
//function to handle back navigation
#objc func addTapped(){
navigationController?.popToRootViewController(animated: true)
}
I'm trying to create a custom navigation bar, and I'm having difficulty modifying different parts of the navigation bar. I can change the color of the background, but I can't seem to add buttons or change the title.
class CustomNavigationController: UINavigationController {
override func viewDidLoad() {
super.viewDidLoad()
// changing the background color works
self.navigationBar.barTintColor = UIColor.purpleColor()
// none of this works
let leftButton = UIBarButtonItem(title: "Info", style: UIBarButtonItemStyle.Plain, target: self, action: #selector(openInfo))
self.navigationItem.leftBarButtonItem = leftButton
self.navigationItem.title = "MYTITLE"
}
}
I'm not sure if the fact that I'm trying to integrate this NavigationController with a TabBarController is affecting the way the view loads, but this custom NavigationController is being subclassed by each tab in the TabBarController.
According to UINavigationItem class reference, each view controller has its own UINavigationItem instance. "The managing UINavigationController object uses the navigation items of the topmost two view controllers to populate the navigation bar with content", which means its UIViewController's responsibility to create the navigation item content such as left bar item or title.
I can understand that you want to provide the same appearance of navigation bar throughout the app. But why do you want to set the same title for all view controllers? However, if same title and same left bar item for all view controllers is what you need. Here are two solutions:
1). Make an extension to UIViewController:
extension UIViewController {
func customAppearance() {
let leftButton = UIBarButtonItem(title: "Info", style: UIBarButtonItemStyle.Plain, target: self, action: #selector(openInfo))
self.navigationItem.leftBarButtonItem = leftButton
self.navigationItem.title = "MYTITLE"
}
func openInfo() {
// do what you want
}
}
And then whenever you need a customised navigation bar for a view controller, you call this customAppearance function:
let vc = YourViewController()
vc.customAppearance()
2). Subclass the UIViewController:
class CustomViewController: UIViewController {
override func viewDidLoad() {
let leftButton = UIBarButtonItem(title: "Info", style: UIBarButtonItemStyle.Plain, target: self, action: #selector(openInfo))
self.navigationItem.leftBarButtonItem = leftButton
self.navigationItem.title = "MYTITLE"
}
func openInfo() {
}
}
And your every other view controllers subclass this CustomViewController.
For customzing UINavigationBar's appearance, you can set it like:
UINavigationBar.appearance().barTintColor = UIColor.purpleColor()
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
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
}
OR
// in your viewDidLoad or viewWillAppear
navigationItem.backBarButtonItem = UIBarButtonItem(
title: "Something Else", style: .plain, target: nil, action: nil)
You can do it from interface builder as follows:
click on the navigation item of previous view controller
from the attributes inspector set the back button text to whatever you want. Thats it!!
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
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.
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:
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
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 :
Swift 4:
self.navigationItem.backBarButtonItem = UIBarButtonItem(title: "", style: .plain, target: self, 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.
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 4.2
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"
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)
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()
For more details,you can see Document:UINavigationBar
Back button text and color text:
navigationController?.navigationBar.tintColor = .red
navigationController?.navigationBar.topItem?.backButtonTitle = "Hi"
In the viewDidLoad method of the presenting controller add:
// hide navigation bar title in the next controller
let backButton = UIBarButtonItem(title: "", style:.Plain, target: nil, action: nil)
navigationItem.backBarButtonItem = backButton
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)
}
}
Swift 4
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"
It works for me. Swift 5
navigationItem.backButtonTitle = ""
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).
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.
Swift 4
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)
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)
Set self.title = ""
before self.navigationController?.pushViewController(vc, animated: true).
override func viewWillAppear(_ animated: Bool) {
self.tabBarController?.navigationItem.title = "Notes"
let sendButton = UIBarButtonItem(title: "New", style: .plain, target: self, action: #selector(goToNoteEditorViewController))
self.tabBarController?.navigationItem.rightBarButtonItem = sendButton
}
func goToNoteEditorViewController(){
// action what you want
}
Hope it helps!! #swift 3
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.
for Swift 4.2
let backItem = UIBarButtonItem()
backItem.title = ""
navigationItem.backBarButtonItem = backItem
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()
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
}
}
There has two of different ways to Implanting that part those are ,
1.
navigationItem.backButtonTitle = "Title Goes Here"
(swift 5)
2.
let backButton = UIBarButtonItem()
backButton.title = "Title Goes Here"
self.navigationController?.navigationBar.topItem?.backBarButtonItem = backButton
