title: How to manage position imageView by Autolayout (iOS)
body: <p>I have a simple imageView and i would like imageView to be aligned:</p>
  
  <ul>
  <li>Vertically/Horizontally. (I have already provided this values)</li>
  <li>I would like image to be proportionally the same on all devices and landscape mode. (Already done by vertical/horizontal alignment)</li>
  <li><strong>I want my imageView to increase/decrease with respect to frame(ipad/iphone)but proportionally to its own size. 64/64, 128/128, 256/256 and etc.</strong></li>
  </ul>
  
  <p>Could you please assist me with respective constraints.</p>
  
  <p>I have tried several ways, but it still now works properly.</p>
