> I know that Voiceover can sometimes work from the top of the screen down when determining tab order, but there must be a reliable way of influencing that so that the tab order makes sense to Voiceover users.

The only option you have other than layout to control reading order is shouldGroupAccessibilityChildren. This property will cause VoiceOver to respect the view's grouping of child elements as a whole rather than intermixing them in the reading order with other views children.

> Also, at times, there is a requirement to move focus into an overlay panel, and then back to the original focus location when the panel closes. Getting that to work as expected is proving a challenge too.

To set focus call UIAccessibilityPostNotification with UIAccessibilityLayoutChangedNotification as the first parameter and the second with the object to set focus to.
