title: How to get a value from a delegate and reload a view
body: <p>I'm developing an iPad app, and it's the first time I put the popover view to good use. I'm using the popover view as a menu with categories, and only have 1 screen with video's. When the user selects a category, the 'FeaturedViewController' has to reload the view with the new playlistId. </p>
  
  <p>When a user selects a category, it's easy to do:  <code>double playlistId = [[playlists.items objectAtIndex:indexPath.row] playlistId];</code></p>
  
  <p>But how do I get that playlistId in my FeaturedViewController and reload the view?</p>
