Accessibility Notification

Overview

Accessibility notifications provide a unified, multiplatform way for your app to convey information to someone using an assistive app. Your app can post these types of notifications:

  • Announcement to convey an announcement to an assistive app
  • Layout change to indicate when the layout of a screen changes
  • Screen change to indicate when a new view appears that occupies a major portion of the screen
  • Page scroll to indicate when a scroll action completes

For announcement notifications, you can set a priority to specify the announcement’s importance relative to other announcements that are in the queue for an assistive app to speak. For more information, see AccessibilityNotification.Announcement .
