Ios Localization not working
===

I have XCode Version 4.3.3 running and iOS 5.1.
i can do what i want. i can't get localization running. i added different languages through project files. I adjusted the InfoPlist.strings in every Language like this:

    "key" = "value";

I have everywhere:

    NSLocalizedString(@"key", nil);

No key is the same like its value. I have checked the which language is chosen:

    NSString * language = [[NSLocale preferredLanguages] objectAtIndex:0];


###But the app constantly just shows the keys and no value when i run the App.###
###I ran out of ideas###

I tried deleting and cleaning everything as described here:

I tried copying the files described here:

And all the files are in their language folder:

Does anybody have an idea what else i can do?!? i don't know what i am doing wrong?!
