I am new to app development and I am trying to create a relatively simple app. The first thing I need to create is a map with some customizable features. I can get the map framework loaded fine and I can get it to run in the simulator with the current location, however I cannot make the map zoom in to my current location nor can I add custom annotations. I have followed many tutorials but I am assuming they are not working because xcode 4.5.2 is so new and is different. If possible could anyone explain the process to me. Ideally I would appreciate if somebody has a code I can copy and paste in order to see what mistakes I am making within my coding.

       //This piece of code zooms into the User Location:
     - (void)mapView:(MKMapView *)mapView


        (MKUserLocation *)userLocation {
            MKCoordinateRegion mapRegion;   
            mapRegion.center = map.userLocation.coordinate;
            mapRegion.span = MKCoordinateSpanMake(0.2, 0.2);
            [map setRegion:mapRegion animated: YES];
        }
