title: Autolayout is not resizing Uicollectionviewcell items when animating between layouts
body: <p>I have a uicollectionview cell with an image view inside that I want to resize when I switch to a larger 'zoomed in' layout.</p>
  
  <p>I have placed constraints inside the cell that does resize the image view when the zoomed in layout is displayed. I am using uicollectionview setLayout animated method. </p>
  
  <p>The problem is the image does not scale with animation only the collection view cell does.</p>
  
  <p>The image seems to just jump into its end size with no interpolation. So the animation looks extremely choppy.</p>
  
  <p>It seems as if I need to somehow control the auto layout constraints so they animate with the set layout animated method but I don't know how.</p>
  
  <p>Is there a proper way to scale the cell and it's contents ?</p>
  
  <p>Thanks so much!</p>
