title: MKPolygonView fillcolor property is not working
body: <p>Below is the code that is not working in some cases. I just need to know the possible reasons for this.
  Problem : .<code>fillcolor</code> property is not working some times polygon is not filled by any color but the border property is working fine.</p>
  
  <pre><code>- (MKOverlayView *)mapView:(MKMapView *)mapView viewForOverlay:(id )overlay
  {
      NSLog(@"inside the viewForOverlay delegate");
  
      NSLog(@"draw polygon inside the viewForOverlay delegate");
      //for draw polygon---
      if ([overlay isKindOfClass:[MKPolygon class]]) {
          MKPolygonView* v = nil;
          v = [[[MKPolygonView alloc] initWithPolygon:(MKPolygon*)overlay]
               autorelease];
  
                  v.lineWidth = 10;
                  v.strokeColor = [[UIColor redColor] colorWithAlphaComponent:1];
                  v.fillColor = [[UIColor greenColor] colorWithAlphaComponent:1];
          return v;
      }
  
      return nil;
  }
  </code></pre>
