How to find city name and other detail from lat/long

Here i m detailing, how to get detail information from lat/long.

for .h file.

import framework

implement MKMapViewDelegate and MKReverseGeocoderDelegate

Declare MKReverseGeocoder *reverseGeocoder;

@property (nonatomic, retain) MKReverseGeocoder *reverseGeocoder;

for .m file.

@synthesize reverseGeocoder;

    CLLocationCoordinate2D coord2d;

        coord2d.latitude =19.3;

        coord2d.longitude =73.9 ;

    self.reverseGeocoder =[[[MKReverseGeocoder alloc] initWithCoordinate:coord2d] autorelease];

 

    Note: If we get data detail for Current location then we can use below statement:

        [[[MKReverseGeocoder alloc] initWithCoordinate:mapView.userLocation.location.coordinate] autorelease];

    reverseGeocoder.delegate = self;

    [reverseGeocoder start];

- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFailWithError:(NSError *)error

{

    NSString *errorMessage = [error localizedDescription];

    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Cannot obtain address."

                                                                                                 message:errorMessage

                                                                                            delegate:nil

                                                                             cancelButtonTitle:@"OK"

                                                                             otherButtonTitles:nil];

    [alertView show];

    [alertView release];

}

- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark

{

     NSLog(@"Thoroughfare : %@",placemark.thoroughfare);

     NSLog(@"Sub-thoroughfare : %@",placemark.subThoroughfare);

     NSLog(@"Locality : %@",placemark.locality);

     NSLog(@"Sub-locality : %@",placemark.subLocality);

     NSLog(@"Administrative Area : %@",placemark.administrativeArea);

     NSLog(@"Sub-administrative Area : %@",placemark.subAdministrativeArea);

     NSLog(@"Postal Code : %@",placemark.postalCode);

     NSLog(@"Country : %@",placemark.country);

     NSLog(@"Country Code: %@",placemark.countryCode);
