iOS Layout Change


Example

In many cases, content within a single screen will update with new or different content. For example, imagine a form that reveals additional options based on the user’s answer to a previous question. In this case, a “layout change” notification lets you either announce the change or focus on a new element. This notification accepts the same parameters as the screen change notification.

UIAccessibilityPostNotification(UIAccessibilityLayoutChangedNotification, firstElement);
