iOS How to save the last tab in UITabBarController

[guydor]

Hi,

I want to open the last tab the user left in UITabBarController.
I used this code but it didn't work:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
	tabBarController.selectedIndex =
    [[NSUserDefaults standardUserDefaults] integerForKey:@"lastOpenedTab"];
	
}


- (void)applicationWillTerminate:(UIApplication *)application {
	NSUserDefaults *lastTab = [NSUserDefaults standardUserDefaults];
	[lastTab setInteger:tabBarController.selectedIndex forKey:@"lastOpenedTab"];
	
}

I'd like to get help

Thanks!

Try putting the restore code in viewWillAppear in the tab view controller...

Then start putting some effort in yourself: log the status of variables (are they nil), log the index you are getting back from the user defaults, check that the tab bar actually has that many tabs (for example if you add them dynamically you may have not done that yet).

Exhaust all the possibilities and you will find the answer.
