iphone - iOS - How to not show a navigation bar on a screen? -

i'm looking way have navigation bar not show on screen @ all.

i know there setnavigationbarhidden:animated: use on navigationbar, still shows bar on screen split second before removing , readjusting screen dimensions.

i've tried moving setnavigationbarhidden:animated: viewdidload:, viewwillappear: etc. , set hidden on previous activities viewwilldisappear: shows on next screen.

how make such view loads out navigationbar on before shown?

thanks, dman

i'm hiding navigation bar uinavigationcontroller in appdelegate - (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions method , works fine me. @ point, while navigating through screens, i'm showing hide again. works charm.

uiviewcontroller *controller = [[uiviewcontroller alloc] init]; uinavigationcontroller *navctrl = [[uinavigationcontroller alloc] initwithrootviewcontroller: controller]; navctrl.navigationbarhidden = yes;  self.window.rootviewcontroller = navctrl; [controller release]; [navctrl release]; 

hope helps.

p.s. never show navigationbar of navigation controller again. on controllers need bar i'm adding new one.
