Answer 1

do like in viewcontroller based hidden using Swift 4.0

To hide navigationController in viewWillAppear

override func viewWillAppear(animated: Bool) {
     super.viewWillAppear(animated)
    self.navigationController?.isNavigationBarHidden = true
}

To unhide navigationController in viewWillDisappear

override func viewWillDisappear(animated: Bool)
{
    super.viewWillDisappear(animated)
    self.navigationController?.isNavigationBarHidden = false
}

Answer 2

If you need to have this navigation bar hidden only in this controller, the best way is to show it in viewWillDisappear() and hide in viewWillAppear().

Answer 3

It's too late to reply and there are other good answers but I would like to share what worked for me.

let controller = self.storyboard?.instantiateViewControllerWithIdentifier("HomeVC")
    self.navigationController!.pushViewController(controller!, animated:true)

Answer 4

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    // Hide the navigation bar on the this view controller
    self.navigationController?.setNavigationBarHidden(true, animated: animated)
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)

    // Show the navigation bar on other view controllers
    self.navigationController?.setNavigationBarHidden(false, animated: animated)
}

Answer 5

in viewDidLoad method of the view controller in which you don't want to show navigation bar add the line

navigationController.navigationBarHidden = true

you are presently hiding in all view controllers

Edit: You are presenting view controller instead it should be

self.navigationController!.pushViewController(controller) 

Answer 6

I am having same requirement in my swift project.

this is how I have handled Navigation bar

Make sure your first screen is embedded into Navigation controller

example we have two screens A and B

In screen A you need to hide navigation bar in viewWillAppear

override func viewWillAppear(animated: Bool)
    {
         super.viewWillAppear(animated)

        //hide navigation for screen A
        self.navigationController?.navigationBarHidden = true
    }

for enabling Navigation in screen B you need to add below code in screen A

override func prepareForSegue(segue: (UIStoryboardSegue!), sender: AnyObject!)
    {
        if (segue.identifier == "screen B's segue identifier here")
        {
           //enable navigation for screen B       
            navigationController?.setNavigationBarHidden(navigationController?.navigationBarHidden == false, animated: true)
        }

    }

Using above style, I can enable or disable navigation bar for specific screen, whenever I want
