Read Current Location Name Using Map View In Iphone

Question

I read the current location's latitude and longitude values and then pin that location in Iphone successfully. Now i want to read that place name using this latitude and longitude values. If anybody have any idea please help me.

Thanks.

I used the following code to read the find the current location..

  - (void)mapView:(MKMapView *)mapView1 didUpdateUserLocation:(MKUserLocation *)userLocation{

 CLLocation *whereIAm = userLocation.location;

NSLog(@"I'm at %@", whereIAm.description);

latitude = whereIAm.coordinate.latitude;

longitude = whereIAm.coordinate.longitude;

NSLog(@"LAT : %f",latitude);

NSLog(@"LONG : %f",longitude);

mapView.mapType=MKMapTypeStandard;

[mapView setMapType:MKMapTypeStandard];

[mapView setZoomEnabled:YES];

[mapView setScrollEnabled:YES];

MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } };

region.center.latitude =latitude; //22.569722 ;

region.center.longitude = longitude; //88.369722;

region.span.longitudeDelta = 0.01f;

region.span.latitudeDelta = 0.01f;

[mapView setRegion:region animated:YES];

[mapView setDelegate:self];

DisplayMap *ann = [[DisplayMap alloc] init];

ann.title = @" Welcome";

ann.subtitle = @"Hi";

ann.coordinate = region.center;

[mapView addAnnotation:ann]; }

  - (void)viewDidLoad {
[super viewDidLoad];

mapView.showsUserLocation = YES; mapView.delegate = self; }

     -(MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation: (id <MKAnnotation>)annotation {

MKPinAnnotationView *pinView = nil;

if(annotation != mapView.userLocation)

{

static NSString *defaultPinID = @"com.invasivecode.pin";

pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];

}

[mapView.userLocation setTitle:@"I am here"];

return pinView;
}

Use the MKReverseGeocoderDelegate Protocol like this :

@interface YourViewController : UIViewController <MKReverseGeocoderDelegate> 
{
}


@implementation YourViewController

- (void)mapView:(MKMapView *)mapView1 didUpdateUserLocation:(MKUserLocation *)userLocation{
     CLLocation *whereIAm = userLocation.location;
     MKReverseGeocoder *reverseGeocoder = [[MKReverseGeocoder alloc] initWithCoordinate:whereIAm.coordinate];
     reverseGeocoder.delegate = self;
     [reverseGeocoder start];
}

Now implement the following method delegate to get the response :

- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark {
      NSLog(@"I'm at %@", placemark.locality);
}
