Image as a left calloutaccessoryView

In native map annotation if you want to show custom image  in annotation and  discloser button as rightCalloutaccessoryView then you can do this by applying this code:

- (MKAnnotationView *)mapView:(MKMapView *)map viewForAnnotation:(id <MKAnnotation>)annotation

{

  static NSString *AnnotationViewID = @"annotationViewID";

        

        MKAnnotationView *annotationView = (MKAnnotationView *)[self.mapView dequeueReusableAnnotationViewWithIdentifier:AnnotationViewID];

        

        if (annotationView == nil)

        {

            annotationView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID] ;

        }

      annotationView.image = [UIImage imageNamed:@"marker.png"];

       UIImageView *_image_view = [[UIImageView alloc] initWithFrame:CGRectMake (0,0,31,31)];

       [_image_view setImage:[UIImage imageNamed:@"marker_similar.png"]];

       annotationView.leftCalloutAccessoryView = _image_view;

       annotationView.rightCalloutAccessoryView = [UIButton         buttonWithType:UIButtonTypeDetailDisclosure];

}
