title: UIScrollView doesnt work for the subViews
body: <p>I have a view with the scrollView implemented into it and it works perfectly fine. But when I add subViews to my parent view, the scrollView works in the background i.e. the parentView and subView doesnt move it will be static. How can I make the whole view scroll? </p>
  
  <p>I have added the subViews as below:</p>
  
  <pre><code>evfView1 = [self.storyboard instantiateViewControllerWithIdentifier:@"EVFView"];
  
   evfView1.view.frame=CGRectMake(0, 517, 1024, 128);
  
  [self.view addSubview:evfView1.view];
  </code></pre>
