title: I have one Query related to background and foreground tableview reload data?
body: <p>hello every one good noon,
  I have one Query related to background and foreground.</p>
  
  <p>In my application in table view cell I display the image from URL with the help of <code>AFNetworking</code> .Ok</p>
  
  <p>Now my Main query is When I scroll up images is displayed in cell and after 20 to 25 images is display in table then I press home button and app goes to background and after some second(10 to 20 sec) when I click on app icon and app comes to foreground and I scroll down then some images is reload .</p>
  
  <p>So it's right or Wrong
  NOTE:- I am not talking about force QUIT (Just foreground to background and again foreground).</p>
