standard - iOS MapKit pines personalizados

Question

¿Cómo muestro imágenes en lugar de pins en el mapa? Hasta el momento solo puedo añadir alfileres de barril. Un código de ejemplo de .m sería de gran ayuda ya que todavía soy nuevo en la programación de iOS.

Answer 1

Vaya al organizador de Xcode y luego vaya a la documentación y busque en weatherMap. Muestra un mapa para incluir imágenes en la anotación.

#pragma mark MKMapView delegate

MKCoordinateRegion region = mapViewOffer.region;
region.center = CLLocationCoordinate2DMake(12.9752297537231, 80.2313079833984);

#pragma mark -

{
    if ([annotation isKindOfClass:[MKUserLocation class]])
        return nil;

EDITAR:

Podría explicarle todo acerca de MKAnnotationView , pero creo que encontrará que la documentación proporcionada por Apple es una explicación mucho mejor que de cualquier otra fuente. Consulte la sección de información general en el enlace.
