Current Location Problem using MKMapView in iPhone?

Question

I am integrating map feature into my application. I have displayed the current location. In my problem is, i am developing two applications and displayed the current location. But both the applications displayed the current location in different location and different view in the map. See my screenshots alt text

Both the screenshots are taken by simulator with two applications and it shows the different Map view frame. But i have used the same code for that.(This happens in device also, show the different place with the map frame). I donno why the map view frame is changed? I have created the map view frame in XIB. And i have included the required frameworks and switched on the location services. Why the Map frame view change? It's weird to me.

Here my sample code is,

  - (void)viewDidLoad {

       [super viewDidLoad];
       self.locationManager = [[[CLLocationManager alloc] init] autorelease];

       self.locationManager.delegate = self; 

       [mapview setShowsUserLocation:YES];

    [locationManager startUpdatingLocation];

}

  - (void)locationManager: (CLLocationManager *)manager didUpdateToLocation: (CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
 {      
    MKCoordinateRegion region1;
    
    region1.center = newLocation.coordinate;

    //Change the Zoom level of the current location

    //region1.span.latitudeDelta = 0.1;//0.0001

    //region1.span.longitudeDelta = 0.1; //0.0001

    mapview.mapType = MKMapTypeStandard;

    //[mapview setRegion:region1 animated:TRUE];

    [locationManager stopUpdatingLocation];

    }

I hope, the first screen shot map view frame is correct. Because i have passed the map view co-ordinates(North East, North West, South East and South West) to the server. If the frame size is wrong, i will get the wrong user details from the server. Please help me out.

Thanks!

The lines in your locationManager:didUpdateToLocation:fromLocation: that are commented out are required for the map view to be updated. You need the call to [mapView setRegion:animated] in order to change the view region. Is your code definitely the same in both applications?

I assume that you know that in the simulator the current location is always the Apple headquarters in Cupertino, as shown in your first screenshot.
