title: UICollectionView VS UITableview
body: <p>I have an app which will show over a 1000 items, all of those item details are local ( saved via coredaata) and will ship with the app.</p>
  
  <p>In researching the UI mechanisms to show those items, I am in between choosing uicollectionview or tableviewcontroller with a customized cell. 
  My question is : Which choice would be more efficient and provide a smoother UI in terms of 
  dragging? 
  which one can I customize to load out the 1000 entries I have only enough the provide a smooth scroll, and load more cells as needed?</p>
  
  <p>Thanks.</p>
