Question

I created a UITabBarController like the following and pushed a navigationController, but I now cannot set the title of tab bar items etc… as the tabbarcontroller is NULL.

Please can you tell me where I am going wrong.

UITabBarController *tabBarController = [[UITabBarController alloc] init];
        LoggedInFeedNavigationController *lvc = [[LoggedInFeedNavigationController alloc] initWithAccount:account];
        [tabBarController setViewControllers:[NSArray arrayWithObject:lvc]];
        [tabBarController setSelectedIndex:0];
        [self presentModalViewController:tabBarController animated:YES];
        [tabBarController release];
        [lvc release];

Answer 1

In the documentation for tabBarController I see the following

If no tab bar is present or the
receiver is a modal view, this
property is nil.

In the comments it says that you are calling self.tabBarController from within the LoggedInFeedNavigationController and I would think it should work properly. But you are displaying the tab bar modally and if the documentation means even if it is inside of UITabBarController as a modal view then that is your problem.
