title: UIActivityIndicatorView with UITableView in Navigation Controller
body: <p>I am working on a an application which is very simple
  a navigation controller with a table view
  when the user clicks a row, he is directed to the details view.</p>
  
  <p>However, the details view pulls data from Core Data. i am pulling a relatively large amount of data that takes about three seconds to load.</p>
  
  <p>I wanted to add that UIActivityIndicatorView to show progress.</p>
  
  <p>I tried to start the animation once the user clicks the row, so i set it to animate in didSelectRowAtIndexPath</p>
  
  <p>For some reason, the Activity Indicator doesn't start before the pushing of the details view. </p>
  
  <p>Any idea why? or the best way to implement such an idea?</p>
