title: display next item in plist NSmutable Array using UIbutton
body: <p>I am developing an iphone app that has a single View containing A UILabel.  The UILabel displays strings from within a plist that is structued as follows;</p>
  
  <pre><code>Root................................................(Array)
  .............Item 0.................................(Dictionary)
  .........................Question...................(String)    "question 0"
  .............Item 1.................................(Dictionary)
  .........................Question...................(String)    "question 1"
  .............Item 2.................................(Dictionary)
  .........................Question...................(String)    "question 2"
  </code></pre>
  
  <p>The Plist is defined as an NSArray and the strings within each Dictionary are called using Constant Keys.</p>
  
  <p>I now want to implement a UIButton that, when pressed, loads the next item from the plist/array into the UILabel.</p>
  
  <p>I need to know specifically what this Action would look like in code because i can't find an example anywhere :(.  Can anybody help with this?</p>
