I want to get the Location name from the Coordinate value in MapKit for iPhone

Question

I want to get the location name from the coordinate value. Here is code,

- (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];      
}

So, From that Latitude and longitude , i want to know that location name.

Hello Friends, Thanks for your answer, i appreciate it, but i got the solution of this, i am not able to post the answer because don't have more than 10 reputation. I will post it after 8 Hours as per the rule of StackOverflow. I just used the google map API to get the Location string after passing the LAt & Long. — Apple, Sep 26 '12 at 11:22

The Below code shall work in ios5 and above

 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");
              }
          }
 ];

-(NSString *)getAddressFromLatLon:(double)pdblLatitude withLongitude:(double)pdblLongitude
{
  NSString *urlString = [NSString stringWithFormat:@"http://maps.google.com/maps/geo?q=%f,%f&output=csv",pdblLatitude, pdblLongitude];
  NSError* error;
  NSString *locationString = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlString] encoding:NSASCIIStringEncoding error:&error];
   // NSLog(@"%@",locationString);

  locationString = [locationString stringByReplacingOccurrencesOfString:@"\"" withString:@""];
  return [locationString substringFromIndex:6];
}

This is a good answer, although it uses Google Maps ... I prefer the standard iOS way to get the location. – Frederic Adda May 25 '15 at 12:40

Now this API is not working for more information please go to this URL https://developers.google.com/maps/documentation/geocoding – nivritgupta Aug 21 '15 at 09:55

Use this method

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

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

In iOS 5.0 and later, you can use CLGeocoder of Core Location framework, as for iOS lower than 5.0, MKReverseGeocoder of Map Kit Framework. Good luck!

Here is block to get address string from current location

in .h file

typedef void(^addressCompletionBlock)(NSString *);

-(void)getAddressFromLocation:(CLLocation *)location complationBlock:(addressCompletionBlock)completionBlock;

in .m file
#pragma mark - Get Address
-(void)getAddressFromLocation:(CLLocation *)location complationBlock:(addressCompletionBlock)completionBlock
{
    //Example URL
    //NSString *urlString = @"http://maps.googleapis.com/maps/api/geocode/json?latlng=23.033915,72.524267&sensor=true_or_false";

    NSString *urlString = [NSString stringWithFormat:@"http://maps.googleapis.com/maps/api/geocode/json?latlng=%f,%f&sensor=true_or_false",location.coordinate.latitude, location.coordinate.longitude];

    NSError* error;
    NSString *locationString = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlString] encoding:NSASCIIStringEncoding error:&error];
    NSArray *jsonObject = [NSJSONSerialization JSONObjectWithData:[locationString dataUsingEncoding:NSUTF8StringEncoding]
                                                          options:0 error:NULL];

    NSString *strFormatedAddress = [[[jsonObject valueForKey:@"results"] objectAtIndex:0] valueForKey:@"formatted_address"];
    completionBlock(strFormatedAddress);
}

and to call function

CLLocation* currentLocation = [[CLLocation alloc] initWithLatitude:[SharedObj.current_Lat floatValue] longitude:[SharedObj.current_Long floatValue]];

    [self getAddressFromLocation:currentLocation complationBlock:^(NSString * address) {
        if(address) {
            NSLog(@"Address:: %@",address);
        }
    }];

I want to get the Location name from the Coordinate value in MapKit for iPhone
