How do I disable the navigation bar shadow in iOS 6 for navigation bars with custom background images?

Question

It seems in iOS 6, a drop shadow is automatically added to the navigation bar even when you set a custom background image. I\'m pretty sure this wasn\'t the case with iOS 5

Answer 1

How about the alternative way:

UINavigationBar.appearance().barStyle = .Black

For the dark navigation bars iOS doesn't show the shadow.
