title: Blue dot for current location not displaying using google maps for iOS
body: <p>I'm trying to implement current locations in my app. Please see my code for the <code>viewDidLoad</code> below:</p>
  
  <pre><code>- (void)viewDidLoad {
      [super viewDidLoad];
  
      [self hideTabBar:self.tabBarController];
  
      // Create a GMSCameraPosition that tells the map to display the
      // coordinate -33.86,151.20 at zoom level 6.
      GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
                                                              longitude:151.20
                                                                   zoom:6];
      mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
      mapView_.myLocationEnabled = YES;
      mapView_.settings.compassButton = YES;
      mapView_.settings.myLocationButton = YES;
      mapView_.accessibilityElementsHidden = NO;
      self.view = mapView_;
  
      // Creates a marker in the center of the map.
      GMSMarker *marker = [[GMSMarker alloc] init];
      marker.position = CLLocationCoordinate2DMake(-33.86, 151.20);
      marker.title = @"Sydney";
      marker.snippet = @"Australia";
      marker.map = mapView_;
  }
  </code></pre>
  
  <p>I can see the map in the iOS simulator (iPhone 4s) with the marker set to Sydney, but no blue dot to be seen anywhere. Is current location perhaps working but the UI element is hidden? </p>
  
  <p>Thanks for any help/suggestions!</p>
