I create a UINavigationController object, but it can't set the title.
class LogInSwitchingViewController: UINavigationController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
self.view.backgroundColor = UIColor.white
self.navigationItem.title = "This is title"
self.navigationBar.tintColor = UIColor.black
let vc1 = UIViewController()
vc1.view.backgroundColor = UIColor.brown
self.pushViewController(vc1, animated: true)
}
You need to update the title
property of the visible view controller, not the navigation controller itself:
let vc1 = UIViewController()
vc1.title = "This is title"
vc1.view.backgroundColor = UIColor.brown
self.pushViewController(vc1, animated: true)
