How to hide a navigation bar from first ViewController in Swift?

How can I hide a navigation bar from first ViewController or a particular ViewController in swift?

I used the following code in viewDidLoad():

override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationController?.isNavigationBarHidden = true
}

and also on viewWillAppear:

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

Both methods hide the navigation controller from all ViewControllers.

     private func setupView() {
            view.backgroundColor = .white
            navigationController?.setNavigationBarHidden(true, animated: false)
        }

Alternative

in viewDidLoad use this settings

title = "Madman"
navigationController?.isNavigationBarHidden = false
navigationController?.navigationBar.prefersLargeTitles = true
navigationItem.largeTitleDisplayMode = .always

Check the constraints of Collectionview, scrollview or tableView

 NSLayoutConstraint.activate([
            tableView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor),
            tableView.bottomAnchor.constraint(equalTo: view.bottomAnchor),
            tableView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
            tableView.trailingAnchor.constraint(equalTo: view.trailingAnchor)
        ])

    /*.  Swift 5  */     
    let controller =  self.storyboard?.instantiateViewController(withIdentifier: "sc_userNavigation") as! UserNavigationViewController
    let navigationController = UINavigationController(rootViewController: controller)
    navigationController.setNavigationBarHidden(true, animated: false)
    navigationController.modalPresentationStyle = .fullScreen
    self.present(navigationController, animated: false, completion: nil)

You could also create an extension for this so you will be able to reuse the extension without implementing this again and again in every view controller.

import UIKit

extension UIViewController {
    func hideNavigationBar(animated: Bool){
        // Hide the navigation bar on the this view controller
        self.navigationController?.setNavigationBarHidden(true, animated: animated)

    }

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

}

So you can use the extension methods as below

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

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

Call the set hide method in view Will appear and Disappear. if you will not call the method in view will disappear with status false.It will hide the navigation bar in complete navigation hierarchy 

 override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    self.navigationController?.setNavigationBarHidden(true, animated: true)
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    self.navigationController?.setNavigationBarHidden(false, animated:true)
}

If you know that all other views should have the bar visible, you could use viewWillDisappear to set it to visible again.

In Swift:

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    navigationController?.setNavigationBarHidden(true, animated: animated)
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    navigationController?.setNavigationBarHidden(false, animated: animated)
}

I use a variant of the above, and isolate sections of my app to be embedded in differing NavControllers. This way, i don't have to reset visibility. Very useful in startup sequences, for example.

In IOS 8 do it like 

navigationController?.hidesBarsOnTap = true

but only when it's part of a UINavigationController

make it false when you want it back

You can do it from the window controller (Swift3)

class WindowController: NSWindowController {

    override func windowDidLoad() {
        super.windowDidLoad()

        window?.titleVisibility = .hidden
    }
}

You can unhide navigationController in viewWillDisappear

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

Swift 3

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

    self.navigationController?.setNavigationBarHidden(false, animated: animated)
}

In Swift 3, you can use isNavigationBarHidden Property also to show or hide navigation bar

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    // Hide the navigation bar for current view controller
    self.navigationController?.isNavigationBarHidden = true;
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    // Show the navigation bar on other view controllers
   self.navigationController?.isNavigationBarHidden = false;
}
