title: How to tell when a subView is removed a UIView
body: <p>Basically i wanted to implement a popup UIView so i followed what was posted here
  <a href="https://stackoverflow.com/questions/5103917/pop-up-uiview-imdb-app-style">POP-UP UIView &quot;IMDB App&quot; style</a></p>
  
  <p>This works very well. However i have one query. My main view is a tableView. so when a view is popped up i disable scrolling in the table. Now when the popup subView is removed, i need to re-enable scrolling. How do i achieve that? i can't use willRemoveFromSuperview because the popup view is loading a different NIB altogether. </p>
  
  <p>Should i use Notifications?</p>
  
  <p>hope i was clear with explaining the scenario.</p>
  
  <p>Thanks in advance!</p>
