title: How to give a location coordinate to plot a point in a map in ios using storyboard?
body: <p>I am creating a map view in a view controller, using storyboard.</p>
  
  <p>When I use the following code.</p>
  
  <pre><code>-(void) mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
  {
      CLLocationDistance distance = 1000;   
      MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(userLocation.coordinate,
                                 distance, 
                                 distance);
      MKCoordinateRegion adjusted_region = [self.mapView regionThatFits:region];
      [self.mapView setRegion:adjusted_region animated:YES];
  }
  </code></pre>
  
  <p>A point is plotted in San Francisco, CA, United States. The
   <code>userLocation</code> coordinates are the predefined value in <code>MapKit.h</code> framework.
  Now I create a</p>
  
  <pre><code>-(void) mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
  {
      CLLocationDistance distance = 1000;
      CLLocationCoordinate2D myCoordinate;
      myCoordinate.latitude = 13.04016;
      myCoordinate.longitude = 80.243044;
      MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(myCoordinate, 
                                                                     distance, 
                                                                     distance);
      MKCoordinateRegion adjusted_region = [self.mapView regionThatFits:region];
      [self.mapView setRegion:adjusted_region animated:YES];
  }
  </code></pre>
  
  <p>Here, the region is displayed having the coordinate in the center. But, no point is plotted at the coordinate position.</p>
  
  <p>How to plot a point or annotation in that coordinate location?</p>
