title: how to Load only visible subviews in UIScrollIVew
body: <p>I'm loading my Feed Data(feedArray) in UIScrollView, i'm loading 10-10 records in the Scrollview at once.</p>
  
  <p>Step 1: First i get 10 records into my feedArray from my webservice.</p>
  
  <p>step 2: now i'm loading the 10 records with in the UIScrollView , it's perfectly fine now.</p>
  
  <p>Step 3: now when i call the webservice again, i'm getting another 10 records, now i added them onto feedArray again, feedArray count is 20 records now. and UIScrollView For loop runs for 20 times</p>
  
  <p>Step 4: Like that i  will call the webservice number of times, every time feedArray will be increment by 10 records.</p>
  
  <p>Result: after Loading number of subviews in scrollview, when it reaches to 250 records, my scrollview is getting stuck and very slow scrolling and finally crashed in all ios devices.</p>
  
  <p>because of overloading the subviews in UIScrollView caused all of this issues, so i need to over come these issues.</p>
  
  <p>NOTE: i am loading 19 types of feeds in my scrollview, each feed contains number of subviews, each feed is a UIView with number of subviews.</p>
  
  <p>Any help will greatly Appreciate.</p>
  
  <p>Thank you guys. </p>
