Segue between two view controllers

Question

On my storyboard (shown above), I have a ViewController which holds an MKMapView with annotations. These annotations hold a disclosure icon, which when tapped, should navigate the user to another ViewController. To do so I've created a push segue between the view controllers. I've then given it an identifier of 'showDetail' and implemented the following code.

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
    [self performSegueWithIdentifier:@"showDetail" sender:self];
}

However I get the following error.

Could not find a navigation controller for segue 'showDetail'. Push segues can only be used when the source controller is managed by an instance of UINavigationController.'

Where am I going wrong? I have tried changing my source UIViewController to a UINavigationController, but the view then just displays as a black screen.

Simplest way to do this is to select the View controller you want to be the root of your navigation hierarchy and choose

Editor > Embed In > Navigation Controller

This creates the new navigation controller and hooks up everything up for you.
