iPhone/iOS: How can I get a list of localized strings in all the languages my app is localized in?

问题

I need to send my server a list of localizations for a particular string.

Meaning, if my app has a string Foo which is localized as @"Foo" in English and @"Фу" in Russian, I'd like to send the server a list such as this:

• String Foo:
  • English: "Foo"
  • Russian: "Фу"

What I think I need to be able to do is:

1. Enumerate localized strings for each language my app is localized for
2. Get the localized version of Foo for each language

How do I do (1) and how do I do (2)?

You can retrieve all of the string keys by reading in English.lproj/Localizable.strings as a dictionary and fetching its keys:

NSString *stringsPath = [[NSBundle mainBundle] pathForResource:@"Localizable" ofType:@"strings"];
NSDictionary *dictionary = [NSDictionary dictionaryWithContentsOfFile:stringsPath];

To get each language's translation, you can iterate over the languages for each English key and use NSLocalizedStringFromTableInBundle:

for (NSString *language in [[NSUserDefaults standardUserDefaults] objectForKey:@"AppleLanguages"]) {
    NSBundle *bundle = [NSBundle bundleWithPath:[[NSBundle mainBundle] pathForResource:language ofType:@"lproj"]];
    NSLog(@"%@: %@", language, NSLocalizedStringFromTableInBundle(@"Testing", @"Localizable", bundle, nil));
}
