title: iOS Autolayout: two views of equal width and equally spaced
body: <p>I am currently having difficulty with AutoLayout. I am using interface builder and am trying to place two uiview blocks of 100 * 100. I need these blocks placed in such a way that 1st block's leading to superview equals to 2nd block's trailing to superview.Further this equals to space between these two blocks and equally changes as per screen width.
  I have tried using stackview
  <a href="https://i.stack.imgur.com/Jsrgc.png" rel="nofollow">giving fixed width to stackview seems to be equally spaced in 4s but not on 6s</a>.Keeping width not fixed results in greater spacing in between blocks <a href="https://i.stack.imgur.com/PQAkG.png" rel="nofollow">as here</a> .</p>
  
  <p>Does it is possible to achieve this through interface builder?
  Great thanks for any help.</p>
