Multiple Localized .strings Files in iOS App Bundle

Question

I have a fairly complicated project, consisting of several large localized sub-projects.

Most of my sub-projects are localized through a single Localizable.s

I was able to reproduce and fix the issue, though the solution does imply there's a bug in NSBundle.

I reproduced it with the following bundle structure:

MyApp.app/
 |
  - MyResources.bundle/
      |
       - en.lproj/
      |
       - fr.lproj/

and code:

  NSLog(@"A key: %@", NSLocalizedString(@"A key", nil));
  NSBundle *bundle = [NSBundle bundleWithPath: [[NSBundle mainBundle] pathForResource: @"MyResources" ofType: @"bundle"]];
  NSLog(@"Current locale: %@", [[NSLocale currentLocale] localeIdentifier]);
  NSLog(@"Bundle localizations: %@", [bundle localizations]);
  NSLog(@"Key from bundle: %@", [bundle localizedStringForKey: @"A key" value: @"Can't find it." table: nil]);
  NSLog(@"Key using bundle macro: %@", NSLocalizedStringFromTableInBundle(@"A key",
                                                                             nil,
                                                                             bundle,
                                                                             nil));

With the locale set to fr_FR (i.e. French) the bundle picked the string from the English strings table - even the string "can't find it" doesn't appear.

Without changing the code, I was able to get the French string using the following structure for the bundle instead:

MyApp.app/
 |
  - MyResources.bundle/
      |
       - Resources/
          |
           - en.lproj/
          |
           - fr.lproj/

It looks like NSBundle still expects the old Mac OS X bundle structure instead of what iOS is supposed to use. So a simple change of bundle structure should solve the problem...
