title: How to use LinkedIn API in iPhone SDK?
body: <p>I want to use the <a href="http://en.wikipedia.org/wiki/LinkedIn" rel="nofollow noreferrer">LinkedIn</a> API in my project, but I haven't found any good tutorials about using LinkedIn API. How to use LinkedIn API? </p>
  
  <p>"A beginners guide/introduction" of "basic concepts" would be helpful.</p>
  
  <p>OK, after googleing around I went to this link <a href="http://developer.linkedin.com/community/apis" rel="nofollow noreferrer">LinkedInAPI</a>.</p>
  
  <p>I filled in the form but I am unable to understand what the "Integration URL" (Example URL where the integration will go live.)</p>
  
  <p>Because I want to use LinkedIn in native iPhone application not on any website?</p>
  
  <p>So after getting keys how do I use those keys and how do I authenticate user and get some profile info,post status like all the things? </p>
  
  <p>I know for authentication there is an Objective-C wrapper <code>MPOAuthMobile</code>. I have also downloaded that but unable to understand. What this cumbersome API uses?</p>
