Improve iOS Example Localization

[ghost]

Description

Add an easy way to change the iOS Example application to use other localizations. This would be useful for testing. Ideally, the example app itself should also be localized.

Detail

Currently, the easiest way to change the language used is by going into the Info.plist file of the iOS Example and adjusting the Localization native development region (CFBundleDevelopmentRegion).
