- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
  MKPointAnnotation* pin = (MKPointAnnotation*)view.annotation;
  CLLocationCoordinate2D endingCoord = CLLocationCoordinate2DMake(pin.coordinate.latitude, pin.coordinate.longitude);
  MKPlacemark *endLocation = [[MKPlacemark alloc] initWithCoordinate:endingCoord addressDictionary:nil];
  MKMapItem *endingItem = [[MKMapItem alloc] initWithPlacemark:endLocation];
  endingItem.name = pin.title;
  
  NSMutableDictionary *launchOptions = [NSMutableDictionary new];
  [launchOptions setObject:MKLaunchOptionsDirectionsModeDriving forKey:MKLaunchOptionsDirectionsModeKey];
  [endingItem openInMapsWithLaunchOptions:launchOptions];
}

이렇게하면 자동으로 목적지가 지정되면서 경로찾기 화면이 나오게 된다.
