How to set a UINavigationController's UINavigationBar class programmatically?

Question

I want to add a Custom UINavigationBar Background.

Is there anyway I can do this completely in code? _navigationBarClass seems to be a private property on UINavigationController.

Answer 1

While not programmatic it can be done via Storyboards by setting the Navigation Bar class. See https://stackoverflow.com/a/42989418/47281.
