  <p>Now after that, when the <code>view</code> load i have to pass in data from other places to this <code>view controller</code>, and then load some other views by code.</p>
  
  <p>The <code>scrollview</code> <code>Content height</code> and height did get updated, and i did place the loading and adding of the views at <code>ViewWillAppear</code>. But even if the content size is bigger than the height of the <code>scrollview</code>, i just can't scroll it.</p>
  
  <p><code>Scroll View</code> Height:<strong>667</strong>. <code>Scroll View</code> Content Height :<strong>1632</strong>
  <code>ContentView</code> Height :<strong>1632</strong></p>
