title: Temporarily remove NSLayoutConstraint?
body: <p>I have a <code>UITableViewCell</code> subclass laid out using AutoLayout, and I’d like a small animation in which the image view transforms, grows a bit and shrinks back.</p>
  
  <p>At present, due to the constraints, the labels on the right side of the image are moving too (as they should be).</p>
  
  <p>I’d like a quick and easy means to temporarily say “leave those labels where they currently are while this animation is running”. Is that something I can do without needing to remove and re-add those constraints, which is a lot of hassle?</p>
