Answer 1

Try the following steps to achieve your header visible on all views.

Step 1: Drag a navigationController into your storyBoard and delete tableView rootViewcontroller comes with the naviagtionController.Connect your NavigationController to your tabBarController.Now,NavigationController available to all your view.

Note: Your storyBoard layout should be look like a below image..

Step 2: Implement following code to your FirstTabBarController.

   override func viewDidLoad() {
    super.viewDidLoad()

    // Apply transparency to NavigationBar.
    navigationController?.navigationBar.setBackgroundImage(UIImage(), for: UIBarMetrics.default)
    navigationController?.navigationBar.shadowImage = UIImage()

    //Setting up scanView background
    let barView = UIView(frame: CGRect(x:0, y:0, width:view.frame.width,height: (navigationController?.navigationBar.frame.height)! + UIApplication.shared.statusBarFrame.height)) 
    barView.backgroundColor=UIColor.green // set any colour you want..
    barView.layer.borderColor = UIColor.black.cgColor
    barView.layer.borderWidth = 3
    navigationController?.navigationBar.addSubview(barView)

   //Setting up labelView
    let label = UILabel()
    label.frame = CGRect(x:25, y:5, width:view.frame.width - 50 , height:((navigationController?.navigationBar.frame.height)! + UIApplication.shared.statusBarFrame.height) - 10)
    label.text = "AMAR LIFE"
    label.textAlignment = .center
    label.textColor = .black
    label.font = UIFont(name: "HelveticaNeue-medium", size: CGFloat(40))
    label.layer.borderColor = UIColor.black.cgColor
    label.layer.borderWidth = 3
    barView.addSubview(label)

}

Answer 2

Subclass UITabBarController. Make the green view a subview of the tab bar controller's main view. Whenever the selected view controller changes (or anything else happens), keep bringing the green view to the front. (Even better, make the green view a layer, not a view, and give it a higher z-position so that it automatically floats in front of all subviews.)

Answer 3

you need to add the following method in every view controller

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(true)
    self.navigationController?.isNavigationBarHidden = false
    self.navigationController?.navigationBar.setBackgroundImage(#imageLiteral(resourceName: "123"), for: .default)
    self.title = "Hi I am tittle"
}

Also if you want to avoid code duplication and do more good just create one parent UIview and write this method in it and then inherit it in all the other views. However both solutions work fine. you can change the title and image according to your needs. Thanks
