title: ios voiceover for UITableView sections
body: <p>Is there some way that I can avoid the section titles of the UITableView from saying "heading" in the voiceover mode after the text on the section is read? I am providing custom views in viewForHeaderInSection: . I have tried setting isAccessibilityElement to NO and accessibilityTraits to UIAccessibilityTraitNone for the custom view that I return in viewForHeaderInSection. But I cannot suppress the callout "heading" in voiceover mode. For e.g. if I set the label in the section as "Dates", it will be read out as Dates "pause" heading.</p>
  
  <p>The reason I need to do this is that some of the sections are just custom messages with 0 rows, they are not really headings of any kind. I do not want to have them as rows within a section.</p>
