I'm doing it as in the example https://github.com/CosmicMind/Samples/tree/master/Projects/Storyboards/NavigationController.
But navigationbar not work. It only shows navigationbar, and nothing changes.
Can you elaborate? By doing it as in the example, does the example work? If so, what are the differences?
It only shows default NavigationBar:

Have you set in Storyboards the class NavigationBar ?
Yes, of course.

And you have done the same for the NavigationController ?
May you show me the code you are using to set the items?
Oh, I mixed up NavigationController with NavigationBar.
All works after adding NavigationBar class.
Nice :) Let's close this up.
