This document discusses localization, which is the process of rendering app content into multiple languages. It involves internationalizing the user interface and code to adapt to different languages and cultures. The steps covered include creating a strings file, localizing the project, adding new languages, adding localized strings to the strings file, and adding preferred languages on the device to determine which localized strings to use. Code examples are provided to get the preferred languages array.

2. What is Localization?
Localization is the process of rendering the
content of your app into multiple languages.
Before you can localize your app, you have to
internationalize it. Internationalization is the
process of making your app able to adapt to
different languages, regions, and cultures. It
involves 2 parts:
User-Interface (.xib, .storyboard)
Code (.m, .swift)

3. Internationalizing User-
InterfaceTo Internationalizing project go to:
Project Editor > Project > Info.

4. Create the Strings File
To create .string file, go to
Project navigator > New file > resource > string file

5. Localize Your Project
Now you are ready to localize your project.
For localize , select the string file > you will see the localize button in the file
inspector.

6. Add a New Language
For adding a new language into your project.
Go to Project Navigator > info > localization tab and click +

7. Add Localized Strings into
String File
The string file has a following syntax to add localized
strings:
“KEY” = “Value”;
Ex : “KEY_HELLO” = “HELLO”; (for English
localization)
The Key should be same in all the localized file.

8. Add Preferred Languages into
DeviceFor adding preferred languages into device go to:
Device Settings > general > language & region > in
Preferred Language Order Add Language

9. Get all Preferred
languages
For getting all the preferred languages you add previously ,
NSLocale is use.
NSLocale is a Foundation class that encapsulates all of the
conventions about language and culture for a particular locale.
The following code returns an array if preferred languages
code (en - English)
NSArray *ArrayAllLanguages= [NSLocale
PreferredLanguages]
