title: How do fix MGTwitterStatusesParser / NSXMLParserDelegate issue
body: <p>I am trying to compile an iPhone app.  The app is quite old (2.0 SDK) and it is giving me the following error.</p>
  
  <p><code>~/Desktop/iphone/MGTwitterEngine/MGTwitterMessagesParser.m:45:0
   ~/Desktop/iphone/MGTwitterEngine/MGTwitterMessagesParser.m:45: warning:
   'MGTwitterStatusesParser' may not respond to '  parser:didEndElement:namespaceURI:qualifiedName:'</code></p>
  
  <p>I can get past these warnings by turning off the treat warnings as errors but I want to fix it instead.  I saw one post that said he fixed it by "putting in the NSXMLParserDelegate".  Can someone explain exactly what that means or what the best way to resolve this issue is?</p>
