      span.longitudeDelta = _mapView.region.span.latitudeDelta * 2;
      MKCoordinateRegion region;
      region.span = span;
      region.center = _mapView.region.center;

     [self.mapView setRegion:region animated:YES];
 }

 - (IBAction)zoomOut:(id)sender {
      MKCoordinateSpan span;
      span.latitudeDelta = _mapView.region.span.latitudeDelta / 2;
      span.longitudeDelta = _mapView.region.span.latitudeDelta / 2;
      MKCoordinateRegion region;
      region.span = span;
      region.center = _mapView.region.center;

     [self.mapView setRegion:region animated:YES];
