Suppress moreNavigationController in custom UITabBarController

Question

I have implemented a custom UITabBar solution for a project. Essentially, if there are more than 5 items, I use a scrollView that will allow the user to scroll through the addit

This is how I ended up fixing this:

- (void) setSelectedViewController:(UIViewController *) selectedViewController {
    self.viewControllers = [NSArray arrayWithObject:selectedViewController];
    [super setSelectedViewController:selectedViewController];
}

Basically any tab from 5 on gets its navigation controller replaced by the moreNavigationController when you intiially set the viewControllers on UITabBarController. Therefore, I dynamically set viewControllers to just contain the tab I'm clicking. There never ends up being more than 1 in this case so the moreNavigationController doesn't come into play.

When I init my custom controller, I just supply the first tab as the viewControllers so the application can load.

- (id) init {
    self = [super init];
    if (self) {
        self.delegate = self;
        [self populateTabs];
    }
    return self;
}

- (void) populateTabs {
    NSArray *viewControllers = [self.manager createViewsForApplication];
    self.viewControllers = [NSArray arrayWithObject:[viewControllers objectAtIndex:0]];
    self.tabBar.hidden = YES;
    MyScrollingTabBar *tabBar = [[MyScrollingTabBar alloc] initWithViews:viewControllers];
    tabBar.delegate = self;
    [self.view addSubview:tabBar];
}

For clarity, the tabBar delegate is set to this class so that it can respond to tab clicks. The delegate method is as follows:

- (void) tabBar:(id) bar clickedTab:(MyScrollingTabBarItem *) tab {
    if (self.selectedViewController == tab.associatedViewController) {
        [(UINavigationController *) tab.associatedViewController popToRootViewControllerAnimated:YES];
    } else {
        self.selectedViewController = tab.associatedViewController; 
    }
    // keep nav label consistent for tab
    self.navigationController.title = tab.label.text;
}
