title: In iOS 8, how to add Row Action Buttons to the left side of a UITableViewCell
body: <p>Apple shows these images on their product page for iOS 8. I am interested in adding buttons to the <em>left</em> side of a table row as shown in the first image. Is this a public API? Note that I am already aware of the delegate method for adding buttons to the right side. I've looked through the WWDC session videos and documentation to no avail. </p>
  
  <p>Thanks in advance. </p>
