Linking a new viewcontroller to Storyboard?

There is probably a simple solution but I can't figure it out.

I am using storyboards for the interface.

I start with a tab bar controller, but before the user is allowed to use the app the user has to authenticate himself trough a loginview which is modally pushed at the start.

I want to configure the loginview at the same storyboard, but I can't seam to figure out how to link the view controller at the storyboard and my code.

What I have done:

No label...

I'm new in this field. But if the first view controller is a navigation view controller and its rootviewcontroller is a table view controller. If you want to push a view controller like the LoginViewController when you click the cell, and you also want to go back to the table view by using the navigation bar. I recommend this way:

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath  {

   UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
   UIViewController *controller = [sb instantiateViewControllerWithIdentifier:@"LoginViewController"];
   [self.navigationController pushViewController:controller   animated:YES];
}

In this way, you can have the navigation.

By the way, I don't know why this kind of problem you asked will appear. I guess when the loginviewcontroller is created in the code, its view is not the view in the storyboard. If someone know the cause, please tell me! thanks!

The answer by Scott Sherwood above is most correct answer I found after lot of searching. Though very slight change as per new SDK (6.1), presentModalViewController shows deprecated.

Here is very small change to above answer.

 UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Storyboard" bundle:nil];
    HomeViewController * hvc = [sb instantiateViewControllerWithIdentifier:@"LoginView"];
    [hvc setModalPresentationStyle:UIModalPresentationFullScreen];
    [self presentViewController:hvc animated:YES completion:nil];

Pull on a new UIViewController that will act as the login view controller onto the MainStoryboard. In the attribute inspector change the identifier to LoginViewController (or something appropriate). Then add

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"LoginViewController"];
    [vc setModalPresentationStyle:UIModalPresentationFullScreen];

    [self presentModalViewController:vc animated:YES];
}

to the First view controller and the login screen will be loaded from your storyboard and presented.

Hope this helps.
