Showing/hiding navigation bar with smooth animation

Question

I have a navigation based app. The first view (rootcontroller) starts with three large buttons only. No navigationbar. From there, everything else is tableviews and have navigation bars. I'm doing this to show/hide the navigation bar:

MyAppAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
appDelegate.navigationController.navigationBar.hidden = NO;

Once I leave the root controller, the navigation bar will jerk into place and lay on top of the tableview, rather than pushing it down. It clips the top part of the tableview. Going back to the root controller isn't smooth in how the navigation bar disappears. Is there a smoother/better way to do accomplish hiding the navigation bar for the root controller only?

Answer 1

You can use [navigationController setNavigationBarHidden: YES animated:YES] to hide the bar smoothly
