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.
You actually have to set your UIViewController as the root controller of a UINavigationController (or pushed through from a view controller w/ a navcontroller). To do that
- Drag a new navigation controller into your storyboard - it will by default be attached to a tableview controller
- Delete the tableview controller Right click on the navgiation controller, and connect the "Root View Controller" property to your existing view controller
- Move the entry point arrow from your view controller to the root view controller
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.
check this steps: 1. to click connection between two view controller. 2. click attribute inspector 3. set identifier to "showDetail". 4. save and run.
