title: Map View cannot add more than 2 annotations (pins)
body: <p>I have a map view in my app, and every time I add a third annotation (pin) it shows the ARGV running error in the mainDelegate.m file?  Code below:</p>
  
  <pre><code>  [super viewDidLoad];
  
      MKCoordinateRegion region = { {0.0,0.0}, {0.0,0.0}};
      region.center.latitude = 53.321927;
      region.center.longitude = -6.250504;
      region.span.longitudeDelta = 0.01f;
      region.span.latitudeDelta = 0.001f;
      [mapview setRegion:region animated:YES];
  
      MapPin *sandford = [[MapPin alloc] init];
      sandford.title = @"Sandford Park";
      sandford.subtitle = @"Ranelagh";
      sandford.coordinate = region.center;
      [mapview addAnnotation:sandford];
  
      MKCoordinateRegion region2 = { {0.0,0.0}, {0.0,0.0}};
      region2.center.latitude = 53.324089;
      region2.center.longitude = -6.252080;
      region2.span.longitudeDelta = 0.01f;
      region2.span.latitudeDelta = 0.001f;
      [mapview setRegion:region2 animated:YES];
  
      MapPin *Cinnamon = [[MapPin alloc] init];
      Cinnamon.title = @"Cinnamon";
      Cinnamon.subtitle = @"Ranelagh";
      Cinnamon.coordinate = region2.center;
      [mapview addAnnotation:Cinnamon];
  
      MKCoordinateRegion region3 = { {0.0,0.0}, {0.0,0.0}};
      region3.center.latitude = 53.325010;
      region3.center.longitude = -6254461;
      region3.span.longitudeDelta = 0.01f;
      region3.span.latitudeDelta = 0.001f;
      [mapview setRegion:region3 animated:YES];
  
      MapPin *Gommels = [[MapPin alloc] init];
      Gommels.title = @"Gommels";
      Gommels.subtitle = @"Ranelagh";
      Gommels.coordinate = region3.center;
      [mapview addAnnotation:Gommels];

  <p>The first two work fine but the third stops the simulator every time</p>
