title: ObjC: Write to .plist, optimized way?
body: <p>Reading this <a href="http://ipgames.wordpress.com/tutorials/writeread-data-to-plist-file/" rel="nofollow">article</a> for instance, writing an NSDictionary to a plist looks pretty easy. Now, if I just want to modify one single row of an existing plist: Is there any way to update the row without re-writing the whole file?</p>
  
  <p>Like "when updating a row in a database table, I don't have to rewrite the whole table"?</p>
  
  <p>Thanks,
  J.</p>
