Objective In this section, you will learn how you can seamlessly internationalize your Titanium apps. We'll look specifically at how you can use external language files to display text in the user's preferred language.

Contents Titanium provides a number of JavaScript functions in the Titanium.Locale namespace for use in localization. It also provides String formatting functions to handle dates, times, currencies, and more. You can even internationalize the name of your app itself. We'll look at those features, as well as how to test your language settings in this section.

Language strings Rather than hard-coding strings into your project, you can use localized strings. Localized strings are replaced at runtime with values appropriate to the user's language. Titanium relies on resources files and string placeholders to accomplish this task.

In your Alloy project create a directory called i18n. Inside the i18n folder, create folders for each language your application will support. Name the folder according to the ISO 639-1 standard. For example, use en for English, es for Spanish, fr for French, etc.

You can also add a suffix to the language directories for variants of languages. However, if you don't plan on adding multiple suffix-ed directories omit the suffix completely. Suffix the folder name with a dash followed by the country's ISO 3166-1 Alpha-2 code. For example, use en-US for American English, en-CA for Canadian English, en-GB for British English, etc. Note that the OS may not support all regional languages.
