Why is the navigation bar not displayed immediately, but only after several transitions on the screens?

the transition between the storyboard is done by code

let storyboard = UIStoryboard(name: "detail", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "Login") as! TwoViewController
self.present(vc, animated: true)

  • You should probably push your view controller instead of presenting – Scriptable Oct 03 '18 at 09:32
  • but how can I do this? – Sergey Verigin Oct 03 '18 at 09:36
  • like this: `self.navigationController?.push(vc, animated: true)` pushing, pushes onto the navigation stack, but presenting works differently it presents over the top and doesn't use the parents navigation controller – Scriptable Oct 03 '18 at 09:37

Since you are presenting the viewcontroller itself, it won't have any Navigation controller. If you need to present the viewcontroller with navigation controller, present NavigationController instead of viewcontroller.

let storyboard = UIStoryboard(name: "detail", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "navigationControllerID") as! UINavigationController
self.present(vc, animated: true)

OR - wrap VC with NavController programmatically.

let storyboard = UIStoryboard(name: "detail", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "Login") as! TwoViewController
let nav = UINavigationController(rootViewController: vc)
self.present(nav, animated: true)

  • Both will work. But you have to use the same storyboard ID(navigationControllerID) in the code as well as Storyboard. – Lal Krishna Oct 03 '18 at 10:15
