[[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObjects:@"de", nil] 
                                          forKey:@"AppleLanguages"];

Answer 1

Use this -> [[NSUserDefaults standardUserDefaults] synchronize];

Edited Post

Put this macro in the Prefix.pch:

#define currentLanguageBundle [NSBundle bundleWithPath:[[NSBundle mainBundle] pathForResource:[[NSLocale preferredLanguages] objectAtIndex:0] ofType:@"lproj"]]

and where ever you need a localized string use:

NSLocalizedStringFromTableInBundle(@"GalleryTitleKey", nil, currentLanguageBundle, @"")

For Setting use this as you are already using:-

[[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObjects:@"de", nil] 
                                          forKey:@"AppleLanguages"];
