iOS MapKit pins personalizados

Question

¿Cómo se muestran las imágenes en lugar de las clavijas en el mapa? Hasta ahora solo puedo agregar pines de barril. Un código de muestra del .m sería de gran ayuda ya que aún soy nuevo en la programación de iOS.

Answer 1

#pragma mark - 
#pragma mark MKMapView delegate 
- (MKAnnotationView *)mapView:(MKMapView *)mapview viewForAnnotation:(id <MKAnnotation>)annotation 
{ 
    if ([annotation isKindOfClass:[MKUserLocation class]]) 
     return nil; 
    static NSString* AnnotationIdentifier = @"AnnotationIdentifier"; 
    MKAnnotationView *annotationView = [mapView dequeueReusableAnnotationViewWithIdentifier:AnnotationIdentifier]; 
    if(annotationView) 
     return annotationView; 
    else 
    { 
     MKAnnotationView *annotationView = [[[MKAnnotationView alloc] initWithAnnotation:annotation 
                     reuseIdentifier:AnnotationIdentifier] autorelease]; 
     annotationView.canShowCallout = YES; 
     annotationView.image = [UIImage imageNamed:@"someImage.png"]; 
     UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; 
     [rightButton addTarget:self action:@selector(writeSomething:) forControlEvents:UIControlEventTouchUpInside]; 
     [rightButton setTitle:annotation.title forState:UIControlStateNormal]; 
     annotationView.rightCalloutAccessoryView = rightButton; 
     annotationView.canShowCallout = YES; 
     annotationView.draggable = YES; 
     return annotationView; 
    } 
    return nil; 
} 

EDIT:

poder explicar a todos ustedes acerca de la MKAnnotationView, pero creo que se encuentra la documentación proporcionada por Apple para ser una explicación mucho mejor que la de cualquier otra fuente. Verifique la sección de visión general en el enlace.

Answer 2

Ir al organizador de Xcode y luego ir a la búsqueda de documentación e weathermap se muestra un ejemplo de un mapa con la inclusión de imágenes en anotación.
