To create a view controller: UIViewController * vc = [[UIViewController alloc] init]; To call a view controller (must be called from within another viewcontroller): [self presentViewController:vc animated:YES completion:nil]; For one, use nil rather than null. Loading a view controller from the storyboard: NSString * storyboardName = @”MainStoryboard”; UIStoryboard *storyboard = [UIStoryboard storyboardWithName:storyboardName bundle: nil]; UIViewController … Read more

I have found out a solution. I have add the following code in HomeViewController.viewDidLoad and that works ! definesPresentationContext = true
