title: Google Maps control missing
body: <p>I added a view in the storyboard, then set the view to GMSMapView. But now the location button and compass in the map is missing. When I add the map programmatically using the instructions from <a href="https://developers.google.com/maps/documentation/ios/start#adding_the_google_maps_sdk_for_ios_to_your_project" rel="nofollow">https://developers.google.com/maps/documentation/ios/start#adding_the_google_maps_sdk_for_ios_to_your_project</a>, the controls of the map appear.</p>
  
  <p>.h class</p>
  
  <pre><code>@interface MapController : UIViewController{
  
      IBOutlet GMSMapView *mapView_;
  
  }   
  </code></pre>
  
  <p>.m class</p>
  
  <pre><code>- (void)viewDidLoad {
      [super viewDidLoad];
  
      GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:mapView_.myLocation.coordinate.latitude longitude:mapView_.myLocation.coordinate.longitude zoom:1];
  
      mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
  
      mapView_.myLocationEnabled = YES;
  
      mapView_.settings.myLocationButton = YES;
      mapView_.settings.compassButton = YES;
  
  }
  </code></pre>
