Changing the animation for UINavigationController NavigationBar

Question

Right now when I use [self.navigationController setNavigationBarHidden:NO animated:YES];

The navigation bar flies in from right to left, is there a way to drop it do

Answer 1

Give this a go:

CATransition *transition = [CATransition animation];
transition.duration = kAnimationDuration;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromTop;
transition.delegate = self;
[self.navigationController.view.layer addAnimation:transition forKey:nil];

self.navigationController.navigationBarHidden = NO;
[self.navigationController pushViewController:tableViewController animated:YES];

Worked great for me.
