how to localize address result from reverseGeocodeLocation?

Question

My iphone app supposed to resolve address based on latitude and longitude of the user. reverseGeocodeLocation works fine, but results are in english.

Is there a way to localize the results to other languages?

couldnt find any information about it at apple or anywhere else.

The code I use is:

CLGeocoder *geocoder = [[[CLGeocoder alloc] init] autorelease];
CLLocation *location = [[[CLLocation alloc] 
       initWithLatitude:coord.latitude longitude:coord.longitude] autorelease];

[geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error) {
    NSLog(@"reverseGeocodeLocation:completionHandler: Completion Handler called!");

    if (error){
        NSLog(@"Geocode failed with error: %@", error);
        [self displayError:error];
        return;
    }
    if(placemarks && placemarks.count > 0)
    {
      //do something
        CLPlacemark *topResult = [placemarks objectAtIndex:0];

        NSString *addressTxt = [NSString stringWithFormat:@"%@ %@,%@ %@", 
           [topResult subThoroughfare],[topResult thoroughfare],
           [topResult locality], [topResult administrativeArea]];
    }
}

i found how to localize country name, maybe it'll help:

CLPlacemark *placemark;

NSString *identifier = [NSLocale localeIdentifierFromComponents: [NSDictionary dictionaryWithObject: placemark.ISOcountryCode forKey: NSLocaleCountryCode]];
NSLocale *usLocale = [[NSLocale alloc] initWithLocaleIdentifier:@"en_US"];
NSString *country = [usLocale displayNameForKey: NSLocaleIdentifier value: identifier];

insert any country id instead @"en_US"

Solution for Swift 4, iOS 11

You can force to get geocoding results in chosen locale language by setting argument: preferredLocale: Locale.init(identifier: "en_US").

CLGeocoder().reverseGeocodeLocation(location, preferredLocale: Locale.init(identifier: "en_US"), completionHandler: {(placemarks, error) -> Void in
    print(location)

    if error != nil {
        print("Reverse geocoder failed with error" + error!.localizedDescription)
        return
    }

    if placemarks!.count > 0 {
        let pm = placemarks![0]
        print(pm.administrativeArea!, pm.locality!)
    }
    else {
        print("Problem with the data received from geocoder")
    }
})

Mattt Thompson has a great writeup on using a method from the AddressBookUI.framework for localizing addresses on his site NSHipster. He also has a formatting library on github which contains a class for doing this type of localization which uses the AddressBookUI.framework approach he has described.

Since iOS11, apple provides us with another API which can set locale to print localized language.

- (void)reverseGeocodeLocation:(CLLocation *)location preferredLocale:(nullable NSLocale *)locale
 completionHandler:(CLGeocodeCompletionHandler)completionHandler API_AVAILABLE(macos(10.13), ios(11.0), watchos(4.0), tvos(11.0));
