I think that you can add and remove the tab in UITabBarController at runtime. This site is good for reading: UITabBarController

Some sample code for removing tabs from tab bar:

- (IBAction)processUserInformation:(id)sender

{

   // Call some app-specific method to validate the user data.

   // If the custom method returns YES, remove the tab.

   if ([self userDataIsValid])

   {

      NSMutableArray* newArray = [NSMutableArray arrayWithArray:self.tabBarController.viewControllers];

      [newArray removeObject:self];



      [self.tabBarController setViewControllers:newArray animated:YES];

   }

}
