Swift calling setNavigationBarHidden but view wont move to top

Question

I am hiding my navigation bar when I scroll by calling: self.navigationController?.setNavigationBarHidden(true, animated: true)

The only problem is that the navbar doesnt get hidden all the way.

Whats even stranger is if I push to a new VC and go back and now try to scroll the navigation bar gets hidden all the way which is what I want.

If it matters I am hiding the navigation bar on VC2 then showing it when I exit back to VC 1.

This is what it looks when I try to hide the navbar first time, it doesnt go up all the way/underlying view showing too much.

If I push the to next VC and go back and now try to hide the navigationbar it works

The my view has a constraint of 0 to top layout so its hugging the top

So how can I make my view always be like in the second image when hiding my navigation bar?

Only way you can do this you have to tweak navigationBar setting and programmically create your own navigationBar and status bar using UIView and take it from there..it worked I am personally using in my project. — Joe, Oct 21 '16 at 01:25

Try this code...

Note: This is a simple approach for your problem. If you want more custom look navBar and status bar look .You should read my previous comment...

Set navigation controller property hidesBarsOnSwipe to true

     override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)

navigationController?.hidesBarsOnSwipe = true

}

About your comment, do you mean that I should init my view with the navigationbar completley hidden and then style a UIView to make it look lika a navigation bar? – user2636197 Oct 21 '16 at 02:29

I understand your question. The green part in your second image is not a navigation bar, it is a status bar. You can hide the status bar as below.

You should implement prefersStatusBarHidden on your view controller(s):

In Swift 2:

override func prefersStatusBarHidden() -> Bool { return true }

In Swift 3:

override var prefersStatusBarHidden: Bool { return true }

No the green is my view. I want my view to always appear like in the second image when I hide my navigation bar. I still want my status bar to be shown, I just dont want that extra space like in the first image – user2636197 Oct 21 '16 at 00:21
I cant since I am hiding the navigation bar when I scroll and not leaving – user2636197 Oct 21 '16 at 00:49
