gps on simulator crashes

The following problem appears only in the iPhone simulator of xcode, on a real device it works!

I set up a mapView and display a map. This works absolutely fine, but when I try to start the gps with [self.mapView.gps start] the application crashes with the following error:

*** Terminating app due to uncaught exception 'CALayerInvalidGeometry', reason: 'CALayer position contains NaN: [nan nan]'

Has this something to do with different spacial references? The map is in GK4.

If someone has a little hint for, that would be very helpful!:)

Here is my code:

// static variables NSString* passauStreetMapUrl = @""; NSString* passauAirMapUrl = @""; NSString* passauPoiLayerUrl = @""; NSString* worldMapUrl = @"";  - (void)viewDidLoad {     [super viewDidLoad];  // Do any additional setup after loading the view.              //set this class as the delegate for the mapview     self.mapView.layerDelegate = self;              //set wrap around vor the world map view     self.mapView.wrapAround = YES;          //create url     NSURL* urlPassauMap = [NSURL URLWithString: passauStreetMapUrl];     NSURL* urlPassauPoiLayer = [NSURL URLWithString: passauPoiLayerUrl];          //create tiled(PassauAirMap) and dynamic(PassauMap with layers) maps     self.layerPassauMap = [AGSDynamicMapServiceLayer dynamicMapServiceLayerWithURL: urlPassauMap];     self.layerPassauPoi = [AGSDynamicMapServiceLayer dynamicMapServiceLayerWithURL: urlPassauPoiLayer];          //add maps to view     UIView<AGSLayerView>* lyrView = [self.mapView addMapLayer:self.layerPassauMap withName:@"layerPassauMap"];     lyrView = [self.mapView addMapLayer:self.layerPassauPoi withName:@"layerPassauPoi"];          //set certain layers of the PassauMap to visible     self.layerPassauPoi.visibleLayers = [NSArray arrayWithObjects:[NSNumber numberWithInt:0], nil];          //better user experience on zooming and panning     lyrView.drawDuringPanning = YES;     lyrView.drawDuringZooming = YES; }

-(void) mapViewDidLoad:(AGSMapView*)mapView {     NSLog(@"INFO: mapViewDidLoad");   [self.mapView.gps start];           if (!mapView.gps.enabled) {   NSLog(@"The GPS is not enabled");  }  else if (mapView.gps.enabled) {   NSLog(@"The GPS is enabled");     }     }
