I have been lead to believe that it is possible to pass a class as a method parameter, but I'm having trouble implementing the concept. Right now I have something like:

   - (id)navControllerFromView:(Class *)viewControllerClass
                          title:(NSString *)title
                      imageName:(NSString *)imageName
{
    viewControllerClass *viewController = [[viewControllerClass alloc] init];
    UINavigationController *thisNavController =
    [[UINavigationController alloc] initWithRootViewController: viewController];

    thisNavController.tabBarItem = [[UITabBarItem alloc]
                                  initWithTitle: title
                                          image: [UIImage imageNamed: imageName]
                                            tag: 3];
    return thisNavController;
}

and I call it like this:

rootNavController = [ self navControllerFromView:RootViewController
	title:@"Contact"
	imageName:@"my_info.png"
];

What's wrong with this picture?
