Yandex SmartCaptcha for iOS

Project structure

• ./StartViewController.swift Host controller from which captcha is invoked

• ./Core directory:

  • SheetPresentationController.swift and SheetTransition.swift are used if captcha is going to be invoked as a sheet. To enable a sheet in a test project, use the isSheetCaptchaMode property of the StartViewController class.

  • ProtectedController.swift: Screen displayed after captcha is successfully passed.

  • ./Core/Settings UI: Settings screen used for testing and invoked after the app starts. This screen is used to invoke StartViewController.

    • Captcha open mode determines whether to bring captcha to the screen right away or only after an unsuccessful verification.
    • Captcha result determines the verification result; if Always success = true, the result will always be considered successful.

• ./Core/Validation directory: Classes for validating the data supplied by captcha following a request to backend.

• ./Core/Web directory contains classes for the following entities:

  • CaptchaWebContainer.swift is a container class for captcha; it includes a link to webView and shares it when switching between controllers.
  • MessageHandler.swift is a class for listening to messages from webView.
  • WebContentController.swift is a controller for displaying webView with a captcha.
