iOS Force geolocation to return city name in a spe

问题:

I've encountered a rather strange situation where the backend developer asked me to force the city name that is returned from performing a geolocation to be in a specific language? For instance have it return København instead of Copenhagen no matter what language the iOS is to. I couldn't find anything on the web regarding this. Your help will be much appreciated. Thanks

Not sure if this is the best and safest solution but you could temporarily change the locale while you make the reverse geo code call and then reset it when you are done.

NSArray *defaultLanguages = [[NSUserDefaults standardUserDefaults] valueForKey:@"AppleLanguages"];
NSArray *languages = [NSArray arrayWithObject:@"da"];
[[NSUserDefaults standardUserDefaults] setObject:languages forKey:@"AppleLanguages"];
[[NSUserDefaults standardUserDefaults] synchronize];
CLGeocoder *geocoder = [[CLGeocoder alloc] init];
CLLocation *location = [[CLLocation alloc] initWithLatitude:coordinate.latitude longitude:coordinate.longitude];
[geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error) {
        CLPlacemark *placemark = placemarks[0];
        NSString *danish = placemark.country;
        [[NSUserDefaults standardUserDefaults] setObject:defaultLanguages forKey:@"AppleLanguages"];
        [[NSUserDefaults standardUserDefaults] synchronize];
}];
