Why won't this UIToolBar appear?

Question

Here is the init method of the root view controller of my navigation controller that I am trying to display the toolbar on:

-(id) initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil{
    self = [super initWithNibName:nil bundle:nil];
    if(self){
        //GUI implementation
        self.navigationController.toolbarHidden = NO;
        UIBarButtonItem *flexiableItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
                                                                                       target:self
                                                                                       action:nil];
        UIBarButtonItem *item1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh
                                                                               target:self
                                                                               action:nil];
        self.toolbarItems = [NSArray arrayWithObjects:flexiableItem, item1, nil];

        UIBarButtonItem* addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd
                                                                                   target:self
                                                                                   action:@selector(addEmployee)];

        self.navigationItem.rightBarButtonItem = addButton;
        self.navigationItem.leftBarButtonItem = self.editButtonItem;
    }
    return self;
}

and here is my delegate application:DidFinishLaunching method in the app delegate:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    BOHomeViewController* hvc = [[BOHomeViewController alloc] initWithStyle:UITableViewStylePlain];

    UINavigationController* navbar = [[UINavigationController alloc] initWithRootViewController:hvc];
    [self.window setRootViewController:navbar]; 

    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];
    return YES;
}

The toolbar is not showing up at all. Could someone point out where I am doing something wrong? Much appreciated.

Move the initializing of your toolbarItems to the initializer you're actually calling ( initWithTableViewStyle: ) and self.navigationController.toolbarHidden = NO; to viewWillAppear as self.navigationController will be nil in your intializer.
