As always, consider whether it's both in your users' interest and worth your time to circumvent the standard system behavior here. — Ben Zotto, Jul 06 '11 at 14:02

Have a look at this: How to force NSLocalizedString to use a specific language

hey i followed your link, its really helpful partly.In one example they are selecting a language on click of a button , but my doubt is can i set it through a pickerview ,i.e on selecting from the list in pickerview the language should change – sujay Jul 07 '11 at 04:30
Have an array of country codes like @"it", @"de" and use it to fill up the picker. Then just use the picker delegate method to switch languages: `- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { [Language setLanguage: [_array objectAtIndex: row]]; //some code to update the view (labels and everywhere different language is used) }`. If I understood your question correctly :) – Dunja Lalic Jul 07 '11 at 22:51

You can do this, but it won't play nicely with the built in localization functions in Foundation (e.g. NSLocalizedString), so you'll need to ignore them and write your own string-getting function, XIB-loading path, etc.

The question and answer here covers how to access localizations in the bundle on the fly like this: Overriding preferred strings localization on the fly for testing

You can force the "AppleLanguages" user default. The example below shows how can be done; in particular here I'm switching the first (default) with the second language.



    NSArray *lang = [[NSUserDefaults standardUserDefaults] arrayForKey:@"AppleLanguages"];
    NSLog(@"current lang: %@",lang);
    [[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObjects:
                                                      [lang objectAtIndex:1],
                                                      [lang objectAtIndex:0],
                                                      nil]
                                              forKey:@"AppleLanguages"];

    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    NSMutableArray *languages = [NSMutableArray arrayWithArray:[defaults objectForKey:@"AppleLanguages"]];

    [languages replaceObjectAtIndex:0 withObject:@"fr"];

    [defaults setObject:languages forKey:@"AppleLanguages"];
    [defaults synchronize];

This is setting the language to French. Just put on position 0 what language you want to be loaded.
