title: Three20 + JSON Parsing
body: <p>I'm using Three20 and want to use JSON to populate my <code>TTPhotoViewController</code>.</p>
  
  <p>If I go to a web address, let's say,</p>
  
  <pre><code>www.bbc.com/jsonoutput
  </code></pre>
  
  <p>I get the following</p>
  
  <pre><code>{"name":"MyName","curNiceDate":"Wed 29 Dec 10","images":["UK\/2010\/12\/29\/1.jpg","US\/2010\/12\/29\/2.jpg","EU``\/2010\/12\/29\/3.jpg","FR\/2010\/12\/29\/4.jpg","FR\/2010\/12\/29\/5.jpg","FR\/2010\/12\/29\/6.jpg","FR\/2010\/12\/29\/7.jpg","FR\/2010\/12\/29\/8.jpg","FR\/2010\/12\/29\/9.jpg"]}
  </code></pre>
  
  <p>I want to pick out images which are in <code>www.bbc.com/images/</code>.</p>
  
  <p>All those directories are locations of images relevant from the above address. How would I go about pulling out this information from the JSON output and make it into a URL which will look like this</p>
  
  <pre><code>www.bbc.com/UK/2010/12/29/1.jpg
  
  www.bbc.com/US/2010/12/29/2.jpg
  
  www.bbc.com/EU/2010/12/29/3.jpg
  
  www.bbc.com/FR/2010/12/29/4.jpg
  </code></pre>
  
  <p>So I can feed it into the TTPhotoView Picker.</p>
  
  <p>Any help please?</p>
