It's Never Early Enough to Start Speaking a Foreign Language (IPhone Application Development)

With the world growing even flatter, and the iPhone available in more than 80 countries, the potential market for your app is considerably larger than just people who speak English. Localizing an application isn’t difficult, just tedious. Some of it you can get away with doing late in the project, but when it comes to the strings you use in your application, you’d better build them right — and build them in from the start. The painless way: Use the NSLocalizedString macro (refer to topic 14) from the very start, and you’ll still be a happy camper at the end.
