Navigation controller title not showing up? - ios

Question

So when I have my OptionsViewController as the rootViewController in the AppDelegate didFinishLaunchingWithOptions...
let rootVC = OptionsViewController()
let navigationController = UINavigationController(rootViewController: rootVC)
navigationController.navigationBar.barTintColor = .white
navigationController.navigationBar.isTranslucent = false
navigationController.navigationBar.tintColor = .black
self.window = UIWindow(frame: UIScreen.main.bounds)
self.window!.rootViewController = navigationController
self.window?.makeKeyAndVisible()
...setting the title of the OptionViewController works if I do this in viewDidLoad():
title = "Route Options"
But when I push OptionsViewController onto the navigation stack the title doesn't show up.
I.e. if I start w/ a different view as the rootViewController in AppDelegate:
let rootVC = HomeViewController()
let navigationController = UINavigationController(rootViewController: rootVC)
navigationController.navigationBar.barTintColor = .white
navigationController.navigationBar.isTranslucent = false
navigationController.navigationBar.tintColor = .black
self.window = UIWindow(frame: UIScreen.main.bounds)
self.window!.rootViewController = navigationController
self.window?.makeKeyAndVisible()
And in HomeViewController I push my OptionViewController like this:
let optionsVC = OptionsViewController()
navigationController?.pushViewController(optionsVC, animated: true)
The title does not show up!
The only way I've managed for the title to show up is by doing (in OptionViewController)
navigationController?.navigationBar.topItem?.title = "Route Options"
But it shows up as the back button rather than in the middle, which is not what I want.
If anyone could tell me how I could set the title so that it is on the middle of the navigation bar when it is pushed onto the navigationController stack that would be great!
Code
AppDelegate.swift
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
let rootVC = HomeViewController()
let navigationController = UINavigationController(rootViewController: rootVC)
let barAppearance = UINavigationBar.appearance()
barAppearance.barTintColor = UIColor.blue
barAppearance.tintColor = UIColor.white
barAppearance.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]
self.window = UIWindow(frame: UIScreen.main.bounds)
self.window!.rootViewController = navigationController
self.window?.makeKeyAndVisible()
return true
}
HomeViewController.swift
class HomeViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, DestinationDelegate {
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let optionsVC = OptionsViewController()
self.definesPresentationContext = false //else going to try and present optionVC on homeVC when in optionVC
navigationController?.pushViewController(optionsVC, animated: true)
}
tableView.deselectRow(at: indexPath, animated: true)
}
}
OptionsViewController.swift
class OptionsViewController: UIViewController, UITableViewDelegate, UITableViewDataSource,
DestinationDelegate, SearchBarCancelDelegate,UISearchBarDelegate,
CLLocationManagerDelegate {
override func viewDidLoad() {
self.title = "Route Options"
}

Answer 1

You need to set the navigationItem.title to desired value. If you want an image you set navigationItem.titleView
override func viewDidLoad() {
super.viewDidLoad()
self.navigationItem.title = "Your title here"
}

Answer 2

For others coming here based on the title, don't forget to set your ViewController class in IB to the appropriate Swift file.
After doing that I was able to set the title without a problem using
self.navigationItem.title = "my title"
or
self.title = "my title"

Answer 3

Try it:
In HomeViewController:
let optionsVC = OptionsViewController()
navigationController?.viewControllers = [optionsVC]
And in your OptionsViewController:
override func viewDidLoad() {
super.viewDidLoad()
navigationController?.navigationBar.isTranslucent = false
navigationItem.title = "Your Title"
}

Answer 4

first you need to set UINavigationBar color and text color .
try this in didFinishLaunchingWithOptions.
let barAppearance = UINavigationBar.appearance()
barAppearance.barTintColor = UIColor.blue
barAppearance.tintColor = UIColor.white
barAppearance.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]
if you want to remove the string after backbutton
add these too
let barItemAppearace = UIBarButtonItem.appearance()
barItemAppearace.setBackButtonTitlePositionAdjustment(UIOffsetMake(0, -60), for:UIBarMetrics.default)
And just set your title in viewDidLoad() or
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
self.title = "Your Title"
}

Answer 5

Just add the below line to set the title for navigation item
self.title = "Title 1"

Answer 6

Using Objective-C I also had the problem that it didn't show me the title but going to the next Scene the title appeared next to the back button.
I don't really know why, but I solved it by programming the relative ViewController of that Scene in Swift instead of Objective-C.
After that, it was enough to use the command:
self.title = "My Title"
and so I was able to write what I want programmatically, using if-statement or other methodologies.
Maybe this could be useful to someone who has this problem with Objective-C.

All you need is initialisation navigationItem.title by string containing any printable symbols in viewDidLoad function. String like "" or " " will not worked.
Like this:
override func viewDidLoad() {
super.viewDidLoad()
navigationItem.title = "."
}
Then code navigationItem.title = "Any string" will work well anywhere in your ViewController.
