OK, I am officially flabbergasted. I started an IOS project some time ago, and juggled around with localization a bit at the start, which became a bit of a mess, because I did not know how to do that properly yet.
Now I have decided to do the localization from scratch, and therefore threw away all the .strings files, and created a proper multi-language structure. I started with empty Localizable.strings files, and run the app to see whether I cleaned up everything properly. With empty Localizable.string files, I assumed my "NSLocalizedString" calls would simply return the key as text. They don't. They still return the old text that I had in the old .strings files.
Just to be sure, I put an NSLog statement under one of the NSLocalizedString calls, as such:
NSString *text = NSLocalizedString( key, nil );
NSLog(@"key=%@ text=%@", key, text);
Then I search my whole harddisk for the text that was returned. No file on my harddisk contains the string that NSLocalizedString returns. And it is a completely different string than the key, so it cannot be constructed by NSLocalizedString either.
Anybody knows how this can happen? Is the old info cached somewhere by XCode? How can I persuade the tool to use the new Localizable.strings files? Obviously, I have already 'clean'ed and rebuilt the whole project.
