title: Wikipedia in ios app
body: <p>I want to integrate wikipedia in my iOS App (is it related to the mediawiki ?)</p>
  
  <p>If so, I would like to know how I would tell wikipedia to give me an article about the <code>o2 arena london</code> (it is a one venue of London city) for example.</p>
  
  <p>What would the url be for this example ?</p>
  
  <p>I have searched in google and i have found this URL:</p>
  
  <p><a href="http://en.wikipedia.org/w/api.php?action=query&amp;prop=revisions&amp;titles=o2%20arena%20london&amp;rvprop=content&amp;format=json&amp;rvsection=0&amp;rvparse=1" rel="nofollow">http://en.wikipedia.org/w/api.php?action=query&amp;prop=revisions&amp;titles=o2%20arena%20london&amp;rvprop=content&amp;format=json&amp;rvsection=0&amp;rvparse=1</a></p>
  
  <p>But this is not providing any data. </p>
  
  <p>Is there any other URL ?</p>
