title: iPhone: "error: ABPerson.h: No such file or directory"... How to use the ABPerson class?
body: <p>I'm trying to use the ABPerson object. The <a href="http://developer.apple.com/mac/library/documentation/UserExperience/Reference/AddressBook/Classes/ABPerson_Class/Reference/Reference.html" rel="nofollow noreferrer">documentation</a> tells me to include ABPerson.h.</p>
  
  <p>Here is basically my code:</p>
  
  <pre><code>#import "ABPerson.h"
  [...]
  -(void) updateImageWithContact:(ABPerson)contact;
  </code></pre>
  
  <p>The problem is that I get an error:</p>
  
  <pre><code>error: ABPerson.h: No such file or directory
  </code></pre>
  
  <p>I did include Addressbook.framework so I don't know what's going on.</p>
  
  <p>If I remove the #import there is no error, but I can't use the ABPerson class.</p>
