My problem is as follows. I created an app that allows users to add posts to rows in TableViewController. It also lets them delete only their posts with `UITableViewCellEditingStyle` by checking if the current user has the same id as the id of the user who created the post. Unfortunately, this way of editing the cells also allows to try to delete others users posts. I would like to make that the delete button only appears when users swipe their posts. I attach [an image of the button](http://i.stack.imgur.com/b6IW6.png) I have been talking about.
