Present storyboard ViewController from another ViewController

Question

I have multiple UIViewControllers in my iOS App's Storyboard. I want to open one of the UIViewControllers (in the storyboard) from a different UIViewController.

I've tried the code below, but it isn't working even though I used it before iOS 5 and it worked fine.

- (IBAction)addNotes:(id)sender {
    NotesViewController *notesView = [[NotesViewController alloc] initWithNibName:@"NotesViewController" bundle:nil];
    [self presentModalViewController:notesView animated:YES];
}

How can I perform this action with iOS 5 Storyboards?
