I'm hitting a problem however with dynamically updating content that's displayed in a UITableView. Each row of the table updates every second or so, but if I try to create each cell's accessibilityLabel at this point then I find that there is a problem with the VoiceOver reading out the selected label keeps interrupting itself as the label contents changes so the
