How to make the naveigation bar and toolba

Answer 1

According to Apple specs, you should never change the frame, bounds, or alpha values of the navigation bar.

To hide (or show) the navigation bar, you can change the navigationBarHidden property or call the setNavigationBarHidden:animated method.
