title: UIMapView: User location annotation is white not pulsing blue in iPad only
body: <p>I've been working with maps for a while so I understand the basics of what needs to happen to show the user's location</p>
  
  <pre><code>map.showsUserLocation = YES; //also have the box checked in .xib
  </code></pre>
  
  <p>set up the locationManager</p>
  
  <pre><code>- (CLLocationManager *)locationManager {
  
  if (locationManager != nil) {
      return locationManager;
  }
  
  locationManager = [[CLLocationManager alloc] init];
  [locationManager setDesiredAccuracy:kCLLocationAccuracyNearestTenMeters];
  [locationManager setDelegate:self];
  
  return locationManager;
  }
  </code></pre>
  
  <p>I've logged and see that I'm hitting the didUpdateUserLocation method</p>
  
  <pre><code>- (void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation {
  
  if (!userLoc)
  {
      //NSLog(@"Mapping - didUpdateUserLocation");
      userLoc = userLocation.location;
  }
  
      [locationManager startUpdatingLocation];
  }
  </code></pre>
  
  <p>and I'm also making sure I don't remove the user's annotation</p>
  
  <pre><code>if (![annotation isKindOfClass:[MKUserLocation class]])
  </code></pre>
  
  <p>...so why is the blue dot showing and pulsing on the iPhone, but showing as a white dot only on the iPad?  (Both devices are iOS 7.1.1)</p>
