Use a regular MKAnnotationView, not the MKPinAnnotationView subclass. Even though you can set the image it isn't guaranteed to stick because it can and will set the pin image back again.

Question
I have changed my MapView pin image but I am getting this problem that some of the point wont change the pin image and some of them change. Where would be the problem? I have added an example.
My Code:
- (MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id <MKAnnotation>)annotation
{
MKPinAnnotationView *pinAnnotation = nil;
MKAnnotationView *pinView = nil;
if(annotation != locationMap.userLocation)
{
static NSString *defaultPinID = @"myPin";
pinAnnotation = (MKPinAnnotationView *)[locationMap dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
if ( pinAnnotation == nil )
pinAnnotation = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID] autorelease];
pinAnnotation.canShowCallout = YES;
pinAnnotation.animatesDrop = YES;
pinAnnotation.enabled = YES;
//pinAnnotation.image = [UIImage imageNamed:@"pin.png"];
pinView.image = [UIImage imageNamed:@"pin.png"];
UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
pinAnnotation.rightCalloutAccessoryView = infoButton;
}
return pinAnnotation;
return pinView;
}
