copied!<p>You might consider swapping view controllers <em>not</em> views, using UINavigationController.</p> <p>In your AppDelegate.h</p> <pre><code>@interface AppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; UINavigationController *navigationController; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet UINavigationController *navigationController; @end </code></pre> <p>And in -[AppDelegate applicationDidFinishLaunching:] instantiate navigationController, thus:</p> <pre><code>[self setNavigationController:[[UINavigationController alloc] initWithRootViewController:mySuperviewController]]; [[self navigationController] setNavigationBarHidden:YES]; // Configure and show the window [window addSubview:[navigationController view]]; [window makeKeyAndVisible]; </code></pre> <p>Then within SuperviewController.m you can instantiate your MainMenuController and MainGameController, as you already do. To start with MainMenuController you could do this in SuperviewController -viewDidLoad</p> <pre><code>[[self navigationController] pushViewController:[self mainMenuController] animated:YES]; </code></pre> <p>You would need to add some smarts to switch directly between mainMenuController and mainGameController - but it wouldn't be difficult.</p> <p>So as not to reload nibs again and again, consider defining accessor methods like this:</p> <pre><code>- (MainGameController*) mainGameController { if (mainGameController == nil) { mainGameController = [[MainGameController alloc] initWithNibName:@"MainGame" bundle:nil]; } return mainGameController; } </code></pre> <p>Also, bear in mind that switching between sibling view controllers involve popping current view controller (e.g., mainMenuController) <em>before</em> pushing other view controller (e.g., mainGameController).</p>
