Product:iOS SDK Product Version:11.0 (15A5361a)
Classification:Serious bug Reproducible:Always
 
Area:
UIKit

Summary:
UINavigationBar is no longer animated when calling -[UINavigationController setViewControllers:animated:]

Steps to Reproduce:
Call -[UINavigationController setViewControllers:animated:] with animation: YES
Or run the attached example.

Expected Results:
UINavigationBar animation should be the same as when -[UINavigationController pushViewController:animated:] is called.

Actual Results:
UINavigationItem is pushed without animation. 
The bug can be reproduced in apps built with an older base SDK as well, which makes it a serious issue, since the push animation will be broken in many places.
