title: Retrieving website via API call from site and display to user
body: <p>I am developing an iphone app.</p>
  
  <p>The first screen of my app shows a list of services available for the user.</p>
  
  <p>The user than selects one of the services and goes to the next screen where they can order that service.</p>
  
  <p>I need to retrieve the list of services using an api call from my website.</p>
  
  <p>What is the the way to do so in IOS without affecting the user experience? I don't want the user to be waiting for me to retrieve the list of services from my site every time they access that page.  </p>
  
  <p>I am using the AFNetworking API to get the list of services now.</p>
  
  <p>Thanks!</p>
