title: How to perform the task in background?
body: <p>As its a quite well-know fact that the processor heavy work needs to be on the Non-UI thread, lets consider it as the Background thread. Now in my case I'm parsing data from feed and then inserting those parsed data into the DataBase. I want to handle this 'Data Parsing' on my <strong>Background thread</strong>, keeping the <code>UI</code> thread <strong>Responsive</strong> to user interactions. Now my idea is to start this parsing as soon as the app launches.</p>
  
  <p><strong>I have absolutely no idea about how to handle threads in IOS.</strong></p>
  
  <p>Please someone help me.</p>
