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. Anyon开发者_如何学JAVAe have any ideas?

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

Your MKMapView is always ready to change to the satellite view. But you are forcing it to be in the standard view.

"You missed the break statement in case 1".

switch (((UISegmentedControl *) sender).selectedSegmentIndex) {
        case 0:
            map.mapType = MKMapTypeStandard;
            break;
        case 1:
            map.mapType = MKMapTypeSatellite;
            break;
        case 2:
            map.mapType = MKMapTypeHybrid;
            break;

        default:
            break;
    }

use this code and hookup at xib with "change the value" to segment controll
