title: Objective-C Delegates: Have another class I call that parses XML. Need to know when its done externally
body: <p>I have a class that calls another class to parse (NSXMLParse) from a URL. Now I would like for the class calling this one to know when it has finished, so that I can populate the UI. I am guessing a delegate would be the way to go but ive never worked with one and would need some guidance as to how this would be wired.</p>
  
  <p>Thanks</p>
