MKMapview change annotation image

- (MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id<MKAnnotation>)annotation {
    NSLog(@"annotion");

    CGSize imgSize;
    MKAnnotationView *pinView = nil;
    static NSString *defaultPinID = @"pin";
    pinView = (MKAnnotationView *)
    [self.m_mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];

    pinView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID];
    pinView.canShowCallout = NO;
    pinView.image = [UIImage imageName:@"blue.jpg"]; 
    return pinView;
}    


- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view{
    view.image = [UIImage imageName:@"orange.jpg"]
}

I added annotations on mapView with image(i.e blue image).When i tap a annotation i changed image (i.e. orange image). then i tap on another annotation change annotation(i.e.orange image) to (i.e blue image) and change selected annotation to (i.e.orange image).any help will be appricated.thanks in advance

Try like this, may be helpful.

Reload all other annotations.

- (void)mapView:(MKMapView *)mapView didSelectAnnotationView (MKAnnotationView *)view{
     for (id<MKAnnotation> annotation in mapView.annotations){
        MKAnnotationView* anView = [mapView viewForAnnotation: annotation];
        if (anView){
            anView.image = [UIImage imageNamed:@"blue.jpg"]; 
        }
     }
     view.image = [UIImage imageName:@"orange.jpg"];
}

Try this

for swift 3.0

for annotation: MKAnnotation in mapView.annotations { 

    let anView = mapView.view(for: annotation)

    if (anView != nil) 
    {
        anView?.image = UIImage(named: "home_pin")
    }
}

view.image = UIImage(named: "home_pin01")
