title: How to set frame of UIView in AutoLayout?
body: <p>First of all I have read <a href="https://stackoverflow.com/a/13748523/744616">this answer</a>. </p>
  
  <p>But somehow, we have requirement to change view programatically. And we have use Autolayout all over. </p>
  
  <p>I have code something like this,</p>
  
  <pre><code> self.containerView.frame = CGRectMake(x,y,30,30);
  </code></pre>
  
  <p>This doesn't work. Though I can hide/show border. But I cannot change frame. </p>
  
  <p>Please suggest any hack if not exact solution. </p>
