Question

I want to be notified when the UITabbarViewController is loaded completely and is being displayed on the screen?

Since it’s inheriting from UIViewController i tried setting the delegate to my appdelegate and implemented viewDidAppear, but it never get’s called.

Any solution??

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{
   self.tabbar.delegate = self;
   //other stuff
}

- (void)viewDidAppear:(BOOL)animated
{
    NSLog(@"asdasd");
}

Answer 1

When you set a delegate of UITabBarController you will only be able to override UITabBarControllerDelegate methods and not UITabBarController methods.

Solution: A

Create UITabBarController from code

Solution: B

Subclass UITabBarController

For both solutions you can either do you code within viewDidLoad or send a NSNotification with the info that the view is fully loaded.
