MKMapView maptype not changing?

I cannot understand why my MKMapView does not want to change to satellite view. This method is called and case 1 is called I have stepped over it but it simply does not change to satellite type it always changes to standard. It only works when it goes back to Map type. Anyone have any ideas?

- (IBAction)mapSatelliteSegmentControlTapped:(UISegmentedControl *)sender
{
    switch (sender.selectedSegmentIndex)
    {
        case 1: //Satellite 
            self.mapView.mapType = MKMapTypeSatellite;
        default:  //Map 
            self.mapView.mapType = MKMapTypeStandard;
    }
}
