чтобы показать маршрут от текущего местоположения до пункта назначения движущегося автомобиля

используйте nvpolyline что-то вроде

• (MKAnnotationView *) mapView: (MKMapView *) mapView viewForAnnotation: (id) аннотация {

  if ([аннотация isKindOfClass:[класс NVPolylineAnnotation]]) {

  return [[[NVPolylineAnnotationView alloc] initWithAnnotation:annotation mapView:map] autorelease];
  

  }

  вернуть ноль; }
