Change annotation pin color on MKMapView - ios

Question

I am trying to change colour of annotation pin on MKMapView by overriding this below:
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
// If it's the user location, just return nil.
if ([annotation isKindOfClass:[MKUserLocation class]])
return nil;
// Handle any custom annotations.
if ([annotation isKindOfClass:[MKPointAnnotation class]])
{
MKPinAnnotationView *pinView = (MKPinAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:#"CustomPinAnnotationView"];
if (!pinView)
{
pinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:#"CustomPinAnnotationView"];
pinView.canShowCallout = YES;
pinView.pinColor = MKPinAnnotationColorGreen;
} else {
pinView.annotation = annotation;
}
return pinView;
}
return nil;
}
Here below are relevant methods:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[self configureView];
}
- (void)configureView
{
// Update the user interface for the detail item.
if (self.detailItem) {
// display map ????
PFGeoPoint *geoPoint = self.detailItem[#"location"];
CLLocationCoordinate2D coordinate = CLLocationCoordinate2DMake(geoPoint.latitude,geoPoint.longitude);
MKPointAnnotation *annotation =[[MKPointAnnotation alloc] init];
annotation.coordinate = coordinate;
// remove previous annotation pin
if([self.mapView.annotations count] == 1) {
[self.mapView removeAnnotation:[self.mapView.annotations objectAtIndex:0]];
}
[self.mapView addAnnotation:annotation];
annotation.title = self.detailItem[#"text"];
MKCoordinateSpan span = {.latitudeDelta = 0.05, .longitudeDelta = 0.05};
MKCoordinateRegion region = {coordinate, span};
[self.mapView setRegion:region];
[self.mapView setCenterCoordinate:self.mapView.region.center animated:NO];
}
}
My problem is pin annotation colour is still shown Red as default not Green as I want. What am I missing here?

Credit to #Anna, add the line below to - (void)configureView
self.mapView.delegate = self;
