Set Navbar hidden = false don't work

i have 2 ViewController

VC A and VC B

VC A => NavigationBar Hidden = true

VC B => NavigationBar Hidden = false

I make a segue from A => B, but the navgiationbar in VC B is not visible.

i have include the following swift code in vc b:

override func viewWillAppear(animated: Bool) {
    self.navigationController?.navigationBarHidden = false
}

Any ideas?

VC A and VC B embedded in Navigation controller here and I have this working.

In VC A i have the following code:

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

and in B I have

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

works perfectly

if you are using 

self.navigationController?.navigationBar.hidden = true;

use this to show Bar

self.navigationController?.navigationBar.hidden = false;

not to use

self.navigationController?.navigationBarHidden = false;

please check that

Do it this way:

In your VC A use this code:

override func viewDidLoad() {
    super.viewDidLoad()
    navigationController?.setNavigationBarHidden(true, animated: true)
}

And in VC B use this code:

override func viewDidLoad() {
    super.viewDidLoad()
    navigationController?.setNavigationBarHidden(false, animated: true)
}

You can do following work around

in your VC A viewWillDisappear 

override func viewWillDisappear(animated: Bool) {
        self.navigationController?.navigationBarHidden = false

    }

The navigation bar and the tool bar should disappear in the storyboard when you change the segue -- that's normal.

Try checking enter image description here

Following should work with iOS 8 for a particular view 

override func viewWillAppear(animated: Bool)
{
  self.navigationController?.navigationBarHidden = false
}

To show on all viewControllers place it in viewDidLoad 

self.navigationController?.navigationBarHidden = false
