座標値から場所名を取得したい。これがコードです、

- (void)viewWillAppear:(BOOL)animated {  
    CLLocationCoordinate2D zoomLocation;
    zoomLocation.latitude = 39.281516;
    zoomLocation.longitude= -76.580806;
    MKCoordinateRegion viewRegion = MKCoordinateRegionMakeWithDistance(zoomLocation, 0.5*METERS_PER_MILE, 0.5*METERS_PER_MILE);
    MKCoordinateRegion adjustedRegion = [_mapView regionThatFits:viewRegion];                
    [_mapView setRegion:adjustedRegion animated:YES];      
}

だから、その緯度と経度から、私はその場所の名前を知りたいです。

以下のコードは ios5 以降で動作します。 

 CLGeocoder *ceo = [[CLGeocoder alloc]init];
 CLLocation *loc = [[CLLocation alloc]initWithLatitude:32.00 longitude:21.322]; //insert your coordinates

[ceo reverseGeocodeLocation:loc
          completionHandler:^(NSArray *placemarks, NSError *error) {
              CLPlacemark *placemark = [placemarks objectAtIndex:0];
              if (placemark) {


                  NSLog(@"placemark %@",placemark);
                  //String to hold address
                  NSString *locatedAt = [[placemark.addressDictionary valueForKey:@"FormattedAddressLines"] componentsJoinedByString:@", "];
                  NSLog(@"addressDictionary %@", placemark.addressDictionary);

                  NSLog(@"placemark %@",placemark.region);
                  NSLog(@"placemark %@",placemark.country);  // Give Country Name
                  NSLog(@"placemark %@",placemark.locality); // Extract the city name
                  NSLog(@"location %@",placemark.name);
                  NSLog(@"location %@",placemark.ocean);
                  NSLog(@"location %@",placemark.postalCode);
                  NSLog(@"location %@",placemark.subLocality);

                  NSLog(@"location %@",placemark.location);
                  //Print the location to console
                  NSLog(@"I am currently at %@",locatedAt);
              }
              else {
                  NSLog(@"Could not locate");
              }
          }
 ];

この方法を使用する

CLGeocoder *geocoder = [[CLGeocoder alloc] init]; 

[geocoder reverseGeocodeLocation: zoomLocation completionHandler:^(NSArray* placemarks, NSError* error){
}
 ];

iOS 5.0 以降でCLGeocoderは Core Location フレームワークを、iOS 5.0 未満でMKReverseGeocoderは Map Kit Framework を使用できます。幸運を！
