title: UITableViewCell insert/add style green plus (+) button - how can I grab this image?
body: <p>I need to grab the image for the UITableViewCellEditingStyleInsert button (green +). Of course, I would like to get it in the regular size and in 2x. I didn't think this would be so difficult, but I am having a hard time finding it. Is there a way to get this without a major hack?</p>
