title: Swift 2 how to expand and collapse a view?
body: <p>I have scrollView in which if there is no data, I need to hide (collapse the space occupied by it) so that the lower view can come upwards.</p>
  
  <p>I tried this code with no luck. Please help me.</p>
  
  <pre><code>if(dataForScroll==0){
  
         var   newFrame:CGRect = self.myScroll.frame;
  
     newFrame.size.height = 0;
     self.myScroll.frame = newFrame
  
  
  
             }
  </code></pre>
