Answer 1

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)
}
