Customizing Localization

Regula SDK supports localization. If any language is required by your application but is not supported by Regula SDK, or you want to change our localized strings, you can add localized strings to resource files and allow the Regula SDK to be presented to the users in their desired system locale.

The list of available strings can be found here.


To do this, simply add the needed strings to strings.xml file.


To get started, include the string resource file named RegulaSDK.strings, which is provided with the latest SDK release version to your project's Resources folder. This file name is required and customization will only work if it is set as specified. Next, navigate to Project Settings → Info and in the Localizations section add desired languages.


Don't forget to include RegulaSDK.strings as a Resource File.

Now you can redefine every string in Regula SDK with the appropriate translated values. This way, when the user has their device's System Language set to a language supported by your application, Regula SDK will utilize the appropriate string resources.


Avoid changing the iOS system language (by using the AppleLanguages pref key) from within your application. This goes against the basic iOS user model for switching languages in the Settings app and uses a preference key that is not documented. At some point in the future, the key name may change and that would break your application.
