    copied!<p>I have done test app following this <a href="http://www.techotopia.com/index.php/An_iOS_6_iPhone_State_Preservation_and_Restoration_Tutorial" rel="nofollow">tutorial</a></p> <p>I try to do the same without using Storyboards and it isn't work. I have enabled state preservation and restoration in AppDelegate. I have assigned restorationIdentifier to all my controllers and their views. I think i have to implement some additional code in AppDelegate to restore rootviewcontroller, but i cannot find the right way to do this.</p> <pre><code>-(BOOL)application:(UIApplication *)application shouldRestoreApplicationState:(NSCoder *)coder { return YES; } -(BOOL)application:(UIApplication *)application shouldSaveApplicationState:(NSCoder *)coder { return YES; } - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease]; // Override point for customization after application launch. UIViewController *viewController1 = [[[StateTestFirstViewController alloc] initWithNibName:@"StateTestFirstViewController" bundle:nil] autorelease]; UIViewController *viewController2 = [[[StateTestSecondViewController alloc] initWithNibName:@"StateTestSecondViewController" bundle:nil] autorelease]; self.tabBarController = [[[UITabBarController alloc] init] autorelease]; self.tabBarController.restorationIdentifier = @"TabBarController"; self.tabBarController.viewControllers = @[viewController1, viewController2]; self.window.rootViewController = self.tabBarController; [self.window makeKeyAndVisible]; return YES; } </code></pre>
