Extended mapView:viewForAnnotation Now No Blue Dot

I have extended MapKit's ability to draw custom annotation images with the following code:

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation{
    NSLog(@"Drawing a cloud on the map");
    MKAnnotationView *view;
    if(annotation != mapView.userLocation){
        view=[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"parkingloc"];
        view.image=[UIImage imageNamed:@"placemarkCloud.png"];
        [view setCanShowCallout:YES];
        [view setRightCalloutAccessoryView:[UIButton buttonWithType:UIButtonTypeDetailDisclosure]];
    }
    else{
        view=
    }
    return view;
}

My question is what should I make view = to in order to retain the iPhone's built in blue dot. You can see that I eliminate my custom image being drawn for the dot, but I don't know how to make it show as default.
