If the question you're asking is, "How do I alert the user to a change in content," you can choose among three solutions.

  1. Post UIAccessibilityNotification(UIAccessibilityLayoutChangedNotification, label) to notify the system that the content has changed and force focus to the label.
  2. Post UIAccessibilityNotification(UIAccessibilityAnnouncementNotification, "Your announcement") to request that the system communicate the string to the user.
  3. Assign the UIAccessibilityTraitUpdatesFrequently trait to your label. The system will periodically announce changes to the content.
