Get the native language for the first time into the app. 1. Assume that the native language is in the Software implementation Language list. The native language is selected by default, but the user is still able to select a different language. 2. If the native language is not in the list of software implementation languages, English is selected by default. The user can still select a different language.

All the controllers in the language to be replaced. Notification of language changes sent when a user selects a language. After the controller receives the language change notification, the control that needs to change the language is set again.
