How to control which UIAccessibilityElement receives focus after posting screen change notification?

Question

I have an overlay with accessible elements. When it disappears, I post UIAccessibilityScreenChangedNotification to cause VoiceOver update.

VoiceOver then picks first element of the screen. How can I make it focus on a specific element by default after posting UIAccessibilityScreenChangedNotification?

Answer 1

When you post the notification you can supply additional information which is either an NSString object that VoiceOver speaks or an accessibility element that VoiceOver moves to.

UIAccessibilityPostNotification(UIAccessibilityScreenChangedNotification, focusItem);
