title: Swipeable table view cell with default action
body: <p>iOS8 now provides a way to create swipeable table view cell with actions.  In Apple's own Mail app, you can also commit to a default action if you drag the cell all the way (Mail app shows More | Flag | Trash and defaults to Trash if you drag all the way and release).  Is there a way to do this in iOS 8?</p>
