Apple

Hello Ted,

based on how the screen looks in your particular case, have you considered/tried:

- posting UIAccessibilityAnnouncementNotification with a string to be spoken (e.g. it would include the new subtotal, like “New subtotal x $”)? This does not change VoiceOver cursor position.

- posting UIAccessibiltiyScreenChangedNotification and passing as argument the same string (this behaves like passing nil, but speaks the passed string before announcing the automatically found element on the screen)?

I do not have a really clear idea of how your app behaves in the screen in question, so cannot really tell which of the two above (if any) would be more suitable.

Best regards,

Boris

We have a running subtotal in our GoPayment app. I¹d like to trigger
VoiceOver to announce the new total whenever a user adds an object to the
shopping cart. We are already doing this visually.

I know Screen Changed Notification is great for letting the user know when
the screen has changed and this is what I would suggest. However, I¹m
wondering if this is still the best method.
UIAccessibilityScreenChangedNotification
<https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIAc
cessibility_Protocol/index.html#//apple_ref/c/data/UIAccessibilityScreenCha
ngedNotification>

If this was HTML, I would do something like this
<span aria-live=³assertive² class=³subtotal">$7.50</span>

I don¹t want VoiceOver to announce everything on the screen, just the
subtotal change.

Thanks
