Ios application multi-language free switch implementation

The first time you enter the application to obtain the local language. 1. if the local language is in the software implementation language list. the local language is selected by default, but you can select other languages. 2. if the local language is not in the software implementation language list, English is selected by default. you can select other languages.

Register the notification in all the controllers that want to change the language. When the user selects a language and sends a language change notification, the controller receives the language change notification and re-sets the control for the language to be modified.
