Developing an app with accessibility in mind

The iOS Accessibility Handbook

The Escape From Blindness application

We are going to develop an Escape Room application called “Escape From Blindness”.

That is you will have to go through different levels by solving problems related to the usage of VoiceOver; the core tool for providing accessibility to blind users on the iOS platform.

Here is the expected result, this application is for demonstration purposes.

The application is a simple app designed to illustrate the core UIAccessibility library concepts.


There is four game modes in the game:


1. A quiz with closed questions: you go to the next level if you select the correct answer.

2. A quiz with open questions: you go to the next level if you type in the correct answer in the provided text field.


3. Rotor based levels: we will use the VoiceOver rotor to validate answers and go to the next level.
4. Custom Actions based levels: we will use UIAccessibilityCustomAction to validate answers, you must select validate all level answers in any order to validate the level.

All of the game will be usable only when VoiceOver is activated; if it is not we will indicate the user how to turn it on.
