New to MapKit. Having problems centering map around a specified point. Here is the code. Not sure why this is not working. We are expecting to see a map centered around Cincinnati, OH. What we are seeing is the default google map of the world.

Any help appreciated.

/ Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {

    [super viewDidLoad];

    CLLocationCoordinate2D mapCoords[2];
    mapCoords[0].latitude = 39.144057;
    mapCoords[0].latitude = -84.505484;
    mapCoords[1].latitude = 39.142984;
    mapCoords[1].latitude = -84.502534;

    MKCoordinateSpan span;
    span.latitudeDelta = 0.2;
    span.longitudeDelta = 0.2;

    MKCoordinateRegion region;
    region.center = mapCoords[0];
    region.span = span;

    [mapView setRegion:region animated:YES];
}
