How can I create a NavigationController in a view-based application?

How shou开发者_如何学Cld I go about creating a NavigationController for use in a view-based application?

Put this code

In delegate .h class

      MyViewController *viewController;

In delegate .m class

 - (void)applicationDidFinishLaunching:(UIApplication *)application {    

UINavigationController *nvcontrol =[[UINavigationController alloc] initWithRootViewController:viewController];

[window addSubview:nvcontrol.view];

[window makeKeyAndVisible];

}

Here "MyViewController" should be replaced by your viewcontroller.

All The Best.
