Allow tapping anywhere on an annotation callout without a callout accessory view

Question

I have a map view that adds annotations more or less like this:

- (MKAnnotationView *)mapView:(MKMapView *)mapView
            viewForAnnotation:(id 

        

Answer 1

- (void)mapView:(MKMapView *)mv annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
    Park *parkAnnotation = (Park *)[view annotation];
    switch ([control tag]) {
        case 0: // left button
        {
            NSURL *url = [NSURL URLWithString:parkAnnotation.link];
            [[UIApplication sharedApplication] openURL:url];
        }
            break;

        case 1: // right button
        {
            // build a maps url. This will launch the Maps app on the hardware, and the apple maps website in the simulator
            CLLocationCoordinate2D coordinate = self.locationManager.location.coordinate;
            NSString *url2 = [NSString stringWithFormat:@"http://maps.apple.com/maps?saddr=%f,%f&daddr=%f,%f",coordinate.latitude,coordinate.longitude,parkAnnotation.location.coordinate.latitude,parkAnnotation.location.coordinate.longitude];

            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:url2]];
        }
            break;

        default:
            NSLog(@"Should not be here in calloutAccessoryControlTapped, tag=%ld!",(long)[control tag]);
            break;
    }
}
