title: CollapsableTableView, UIViewControllerHierarchyInconsistency error in iOS6
body: <p>I have an iPhone application which uses a CollapsableTableView. After upgrading to iOS 6 I get a crash in the application with the following error.</p>
  
  <blockquote>
    <p>"A view can only be associated with at most one view controller at a time! View  is associated with CollapsableTableViewHeaderViewController: 0x8a93430. Clear this association before associating this view with CollapsableTableViewHeaderViewController: 0x8a943c0" </p>
