title: What's the preferred way to set accessibility label on UIActionSheets
body: <p>Looking at adding KIF to our app for integration testing.  I'd like to be able to select a button from a UIActionSheet but it doesn't seem like there's an efficient way to set the accessibility labels on each button in the action sheet.</p>
  
  <p>I'm looking at using the accessibleElementCount, iterating through the buttons that way.  Is that the preferred way to do this or is there a more standard way of setting up accessibility for UIActionSheets?</p>
