The code you are doing is correct, but at this point the system will trigger it's own event and override yours.

What you can try to do is post a notification with a delay. But that will result in focus jumping around a little bit when opening the view.

It's not much of an answer, but that is where I'm at at the moment. I'll update you if I figure out a way to do it.

This answer may be of help.

Basically you need to wrap your elements in a container view if they're not in one already and then override the methods specified.

By giving your desired element a tag that is lower than the other elements you can have the view sort the array to ensure that it will be the first element in the accessibilityElements array used by VoiceOver. Or you can adapt the sort method to sort another way.
