Saving UITabBar settings in StoryBoard

Question

When I create deafault Tab Bar application in Xcode i get Storyboard, AppDelegate and two Controller for default tabs. And what i want to achieve is to save last opened tab after restarting application e.g I'm doing something in the second tab bar and I need to close app. But when i run it again it automatically opens in the second tab.

I saw in 'The iOS 5 Developer's cookbook' that you need to create new method for this (tabBarController:didEndCustomizingViewControllers:changed:) but I have no clue where to put ths as I only have AppDelegate and no Controller for the whole UITabBarController and I'm trying to do this with Storyboard.

Answer 1

UITabBarController *tabbar = [[UITabBarController alloc] init];

// Set selected tab bar Number in UITabBarController Delegate Method
//    - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController;
[[NSUserDefaults standardUserDefaults] setInteger:[tabbar selectedIndex] forKey:@"selectedIndex"];
[[NSUserDefaults standardUserDefaults] synchronize];


// Retrive the selectedIndex in Method
//    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
NSInteger selectedIndex = [[NSUserDefaults standardUserDefaults] integerForKey:@"selectedIndex"];
//Now set your selected Tabbar
[tabbar setSelectedIndex:selectedIndex];
