title: "This UIView seems to be the delegate of an NSISVariable it doesn't know anything about. This is an internal UIKit bug" Error
body: <p>I am working on an opengl project. 
  I have used some images (2 for x-y scales) and labels (8) to display the scale on the screen. 
  My first view is a <code>tableview</code> from which I go to <code>openglView</code>. But whenever I go back from <code>openglView</code> to the <code>tableView</code> it gives me this error and app crashes. </p>
  
  <p><strong>"This UIView seems to be the delegate of an NSISVariable it doesn't know anything about. This is an internal UIKit bug."</strong></p>
  
  <p>ANY Suggestions?
  Is this happening because I am including too many UI elements, other than those images and labels I have used some buttons also. And I am applying <code>affineTransform</code> to those images and labels and one button also.</p>
  
  <p><strong>Exact error is:</strong></p>
