title: Overlay on MapView animated
body: <p>I add an overlay (array of multiple coordinates) and draw a path.</p>
  
  <p>It works perfectly, but I would like (if it's possible), to draw the path with an animation (coordinate by coordinate, or fade in, etc.)</p>
  
  <p>My app is only on iOS 7 or later.</p>
  
  <p>Here my methods:</p>
  
  <pre><code>- (void)drawPathWithAnnotations:(NSArray*)annotations
  {
      CLLocationCoordinate2D array[[annotations count]];
  
      for (CLLocation *loc in annotations)
      {
          array[[annotations indexOfObject:loc]] = CLLocationCoordinate2DMake(loc.coordinate.latitude, loc.coordinate.longitude);
      }
  
      self.routeLine = [MKPolyline polylineWithCoordinates:array count:[annotations count]];
  
      [self.mapview addOverlay:self.routeLine];
  }
  
  - (MKOverlayRenderer *)mapView:(MKMapView *)mapView rendererForOverlay:(id&lt;MKOverlay&gt;)overlay
  {
      if(overlay == self.routeLine){
  
          MKPolylineRenderer* lineView = [[MKPolylineRenderer alloc] initWithPolyline:self.routeLine];
          lineView.strokeColor = UIColorFromRGB(kAppTintColor);
          lineView.lineWidth = 3;
  
          return lineView;
      }
  
      return nil;
  }
  
  - (void)mapView:(MKMapView *)mapView didAddOverlayRenderers:(NSArray *)renderers
  {
     // Animation here ? 
  }
  </code></pre>
  
  <p>Thank you, any suggestions or ideas are appreciated! :)</p>
