title: How to display a grid of more than 1000 thumbnails as ui views in UI Scrollview with smooth scrolling
body: <p>I have to implement a application which displays a grid view of thubmnails each of which is a clickable object. The grid view will display 2 images( which i suppose can be a uiview). And 4 rows per page.</p>
  
  <p>The use should be able to smoothly scroll through the image grid view. The images for the thumbnails will be fetched from the url i get from server. However assuming i have the urls in my model how can i implement this feature to display them.</p>
  
  <p>Few problems i have encountered are:</p>
  
  <ol>
  <li><p>All the images(UIviews) cant be loaded due to memory constraints. Hence paging can be enabled.</p></li>
  <li><p>On implemented paging using uiscrollview delegate the ui becomes irresponsive for some time. I am downloading the images in a NSOperation queue and posting the image on mainthread for displaying on screen.</p></li>
  </ol>
  
  <p>I want the scrolling to be very smooth without jerky feature. 
  How can i implement this?</p>
  
  <p>TIA,
  Praveen S</p>
