title: Trying to change MKPointAnnotation colour but losing the title
body: <p>I am trying to change my pin colour to purple, when I do it I lose the title though. Code is:</p>
  
  <pre><code>- (void)viewDidLoad {
      [super viewDidLoad];
  
      self.navigationController.navigationBarHidden=YES;
  
      //init the location manager
      self.locationManager = [[CLLocationManager alloc] init];
      self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
      [self.locationManager requestWhenInUseAuthorization];
      self.mapView.showsUserLocation=YES;
  
      self.userGeoPoint=self.message[@"userLocation"];
      self.pinView = [[MKPointAnnotation alloc] init];
  
      self.pinView.title=self.message[@"fromUser"];
      self.coord = CLLocationCoordinate2DMake(self.userGeoPoint.latitude, self.userGeoPoint.longitude);
      self.pinView.coordinate=self.coord;
      //use a slight delay for more dramtic zooming
      [self performSelector:@selector(addPin) withObject:nil afterDelay:0.5];
  }
  
  -(void)addPin{
  
      [self.mapView addAnnotation:self.pinView];
      [self.mapView selectAnnotation:self.pinView animated:YES];
      MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(self.coord, 800, 800);
      [self.mapView setRegion:[self.mapView regionThatFits:region] animated:YES];
  
  }
  
  -(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id&lt;MKAnnotation&gt;)annotationPoint
  {
      if ([annotationPoint isKindOfClass:[MKUserLocation class]])//keep the user as default
          return nil;
  
      static NSString *annotationIdentifier = @"annotationIdentifier";
      MKPinAnnotationView *pinView = [[MKPinAnnotationView alloc]initWithAnnotation:annotationPoint reuseIdentifier:annotationIdentifier];
      pinView.pinColor = MKPinAnnotationColorPurple;
      //now we can throw an image in there
  
      return pinView;
  }
  </code></pre>
  
  <p>I tried setting the title property for MKPinAnnotation but there isn't one. Is there anyway I can get around this?</p>
