iOS 11 prefersLargeTitles Weird Transition

Question

So I'm having a weird issue with the new large titles in iOS 11. Instead of me trying to badly and confusingly explain the issue here is a 10-second screen recording of what is happening:

Screen recording of issue on YouTube

As you can see there is a weird black bar that appears when transitioning between a view controller that has

navigationItem.largeTitleDisplayMode = .never

And one that is set to .always

Thanks in advance!

Before the transition set this:

self.navigationController?.view.backgroundColor = .white

If you're navbar is a different color, instead of setting it's backgroundColor to white, set it to that color – sbru Jan 09 '18 at 22:07
In which method shall I implement this? – Naveen George Thoppan Aug 24 '18 at 16:26

As Pranav said, the issue here is the background colour of the navigation controller's view, however, changing that from a child view controller is not the perfect way to do it.

Instead, a better way is to subclass UINavigationController and in the viewDidLoad() set the

override func viewDidLoad()
{
  super.viewDidLoad()
  view.backgroundColor = .white
}

Then, just use your custom subclass rather than the standard UINavigationController. This way, you only ever need this code in one place.
