Navigation Bar on only one view in my whole app - ios

Question

I have several views in my app, and I only want a navigationbar on one of them.... I used a navigationcontroller and at first I was using this code (while my app was in its infancy and only had 2 views)
override func viewWillAppear(_ animated: Bool) {
self.navigationController?.setNavigationBarHidden(true, animated: animated)
super.viewWillAppear(animated)
}
override func viewWillDisappear(_ animated: Bool) {
self.navigationController?.setNavigationBarHidden(false, animated: animated)
super.viewWillDisappear(animated)
}
It worked fine - however, the app has become more complex - I have these views
lazy var orderedViewControllers: [UIViewController] = {
return [self.newVc(viewController: "pageOne"),
self.newVc(viewController: "pageTwo"),
self.newVc(viewController: "pageThree"),
self.newVc(viewController: "pageFour"),
self.newVc(viewController: "activate")
]
}()
Where this code isn't applied to, even if I create a custom view controller for each view.
I thought the way to do this would be to put the top chunk of code in every view, but it's not working for the bottom chunk. In essence my question is how do I use NavigationController to create a bar ONLY on one view.

Answer 1

One option: use a "base view controller" class which handles hiding / showing the Navigation Bar, and make your "pages" sub-classes of the "base" class.
import UIKit
class BaseViewController: UIViewController {
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
self.navigationController?.setNavigationBarHidden(true, animated: animated)
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
self.navigationController?.setNavigationBarHidden(false, animated: animated)
}
}
class ViewController: UIViewController {
// has buttons with
// Show (e.g. push)
// segues to Settings, First, Second, Third view controllers
}
class SettingsViewController: UIViewController {
// Settings VC is a normal UIViewController, because
// we *want* the NavBar to remain visible
}
class FirstViewController: BaseViewController {
#IBAction func backTapped(_ sender: Any) {
self.navigationController?.popViewController(animated: true)
}
}
class SecondViewController: BaseViewController {
#IBAction func backTapped(_ sender: Any) {
self.navigationController?.popViewController(animated: true)
}
}
class ThirdViewController: BaseViewController {
#IBAction func backTapped(_ sender: Any) {
self.navigationController?.popViewController(animated: true)
}
}

You can use this method of UINavigationControllerDelegate
optional func navigationController(_ navigationController: UINavigationController,
willShow viewController: UIViewController,
animated: Bool){
if viewController == self."desired view controller" {
self.isNavigationBarHidden = true
}else{
self.isNavigationBarHidden = false
}
}

Thank you all for the support. I have resolved my issue by doing the following:
I put the only view controller I wanted to have a navigation bar in a navigation controller view the Embed menu.
I added a custom back button.
