Menu
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 down top to bottom?

Change the Bar Style A user changes the navigation bar's style, or UIBarStyle , by tapping the “Style” button to the left of the main page. This button opens an action sheet where users can change the background's appearance to default, black-opaque, or black- translucent.
Go to the ViewController. swift file and add the ViewDidAppear method. a nav helper variable which saves typing. the Navigation Bar Style is set to black and the tint color is set to yellow, this will change the bar button items to yellow.
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.
