In Swift, the navigation Bar dissappear and never comes back

Question

I am trying to push a new view controller from the current controller with the push of a button. But as soon as the new controller is presented, the navigation bar from the top disappear and I have tried numerous ways but just cant seem to get it back.

I am doing all my code programmatically without any use of the Interface Builder.

I have tried the list of below codes but none of them worked.

  override func viewDidLoad() {
    super.viewDidLoad()
self.navigationController?.setNavigationBarHidden(false, animated: false)
    self.navigationItem.leftBarButtonItem = UIBarButtonItem(image: #imageLiteral(resourceName: "backimg"), style: .plain, target: self, action: #selector(backTapped))

    let webV:UIWebView = UIWebView(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height))
    webV.loadRequest(NSURLRequest(url: NSURL(string: "https://*****************.com")! as URL) as URLRequest)
    webV.delegate = self;
    self.view.addSubview(webV)
    self.navigationController?.navigationBar.isHidden = false
    navigationController?.isNavigationBarHidden = false
}

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(true)
    self.navigationController?.navigationBar.isHidden = false
    self.navigationController?.setNavigationBarHidden(false, animated: false)
}
override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(true)
    self.navigationController?.navigationBar.isHidden = false
    self.navigationController?.setNavigationBarHidden(false, animated: false)
}

@objc func backTapped(_ sender: Any){
    self.dismiss(animated: true, completion: nil)

}

I am trying to push the view controller from the target function of the button as follows :

  @objc func parkingTimerTapped(_ sender: Any) {
    let pp = ParkingModeScheduleView()

    self.present(pp, animated: true, completion: nil)
    print("Parking Timer Tapped")
 }

I have also already tried to push the view controller using the command below :

  self.navigationController?.pushViewController(pp, animated: true)

Am I doing something wrong or missing something?

Answer 1

you need to add your parkingModeScheduleview in UINavigation controller like this

@objc func parkingTimerTapped(_ sender: Any) {
    let pp = ParkingModeScheduleView()
    let navigation = UINavigationController(rootViewController: pp)
    self.present(navigation, animated: true, completion: nil)
    print("Parking Timer Tapped")
 }
