title: MapKit User Location (Blue Dot & Circle) will not show
body: <p>I cannot figure out why the current location circle will not appear. I have custom annotations that appear just fine... and the map is taken to the current location of the user... but, the circle is not appearing.</p>
  
  <p>Here is my code. Thanks in advance!</p>
  
  <pre><code>- (void)viewDidLoad {
      [super viewDidLoad];
  
   locationManager = [[CLLocationManager alloc] init];
   [locationManager setDelegate:self];
   [locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
   [locationManager startUpdatingLocation];
  
   [mapView setMapType:MKMapTypeStandard];
   mapView.showsUserLocation = YES;
  
   MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } };
   region.span.longitudeDelta = 0.005;
   region.span.latitudeDelta = 0.005;
   [mapView setRegion:region animated:YES]; 
   [mapView setDelegate:self];
  }
  
  - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation  {
      CLLocationCoordinate2D loc = [newLocation coordinate];
      [mapView setCenterCoordinate:loc];      
      }
  
  -(MKAnnotationView *)mapView:(MKMapView *)map viewForAnnotation:(id &lt;MKAnnotation&gt;)annotation {
      static NSString *AnnotationViewID = @"annotationViewID";
      MKAnnotationView *annotationView = (MKAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:AnnotationViewID];
  
      if (annotationView == nil) {
          annotationView = [[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID] autorelease];
          }
  
      annotationView.canShowCallout = YES;
  
      if ([annotationView.annotation.title isEqualToString:@"One"]) {
          UIImage *pinImage = [UIImage imageNamed:@"one.png"];
          [annotationView setImage:pinImage];
      }
  
      if ([annotationView.annotation.title isEqualToString:@"Two"]) {
          UIImage *pinImage = [UIImage imageNamed:@"two.png"];
          [annotationView setImage:pinImage];
      }
  
      annotationView.annotation = annotation;
          return annotationView;
  
      }
