I have a regular UINavigationController and I push a series of UIViewController into the stack. The view transition for push controller is horizontal animation transition: [self.navigationController pushViewController:controller animated:YES];

However, when I press the Back button on the navigation bar, the view transition animation is vertical (vertically dropping down the previous controller/view).

I don't seem to find any way to make this horizontal. This happens only in Landscape mode. Portrait mode the transition all happens as horizontal flip transition.

Can anyone shed any light on this?

Thanks
