title: Constraining UITableViewCell to change when editing
body: <p>I have a UITableViewCell that has a UIImageView 20 pts in from the left. When I tap "Edit" to edit the contents of my UITableView and the red edit circle comes in from the left, how do I properly set up my constraints so the left of my UIImageView is constrained to the right of that red edit circle view? </p>
  
  <p>Note: I'm doing layout in code, not using Storyboards or xibs </p>
