Presenting a View Controller after login

Question

I recently started a new project and after I successfully set up a login page, I came into a problem.

If I type in valid credentials in the text fields, my app should do the following:

if (user) {
    [self.delegate loginViewControllerDidLogin:self];
    ...

The "if user" part means that everything was okay. After a few hours of searching I got to know that my [self.delegate loginViewControllerDidLogin:self]; should be defined in the AppDelegate.m file. Here I wrote the following code:

- (void)loginViewControllerDidLogin:(LoginViewController *)controller {
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    UIViewController * ViewController = [[UIViewController alloc] init];

    [self.window addSubview:ViewController.view];
    [self.window.rootViewController presentViewController:ViewController animated:YES completion:nil];
}

My problem is that I cannot define the ViewController on my story board, so I cannot connect the code with the ViewController itself.

So basically I would like the app to open a new ViewController after logging in.

On your storyboard select the view controller you want to display and fill out the "Storyboard ID":

Then instantiate it like this:

  UIViewController * ViewController = [storyboard instantiateViewControllerWithIdentifier:@"YourVCStoryboardID"];
