A blind tester of mine suggested the use of simple vocal notifications instead of the full blown ones, totally useless to them and just wasting battery life. So I thought of employing:
UIAccessibilityPostNotification(UIAccessibilityAnnouncementNotification,"string")
for that. Too bad the string is not read while the app is in background as I could test by executing the app in the remote fetch target. Is there some way to trigger just voice notification even in background for VoiceOver users?
