title: Unrecognized Selector Sent to UIView Instance Error
body: <p>I know theres a few solutions to this error on StackOverflow already, but I couldn't find one specific to my problem.</p>
  
  <p>I'm trying to create a custom view for the Google Maps marker info windows using:</p>
  
  <pre><code>- (UIViewController *)mapView:(GMSMapView *)mapView markerInfoWindow:(GMSMarker *)marker {
  
  DMinfoWindow *view =  [[[NSBundle mainBundle] loadNibNamed:@"DMinfoWindow" owner:self options:nil] objectAtIndex:0];
          view.firstName.text = self.firstName;
          return view;
      }
  </code></pre>
  
  <p>I have created a UIViewController called DMinfoWindow, which has the a UILabel named firstName and is linked to an IBOutlet.</p>
  
  <p>If I comment out the "view.firstName.text = self.firstName;" line, it works fine and when I click on a marker the custom view appears.</p>
  
  <p>However, with the line included I get the following error:</p>
  
  <pre><code>2013-06-23 17:58:52.763 ExerciseBuddy[1406:1a003] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIView firstName]: unrecognized selector sent to instance 0x1623a6e0'
  </code></pre>
  
  <p>Any help on this error would be great! I assume that something is not in memory that should be but I'm not sure what.</p>
  
  <p>Many thanks</p>
