title: Xcode, see where a method is used
body: <p>I have a method in some class and i would like to see exactly where it is being used. Compared to Java and Eclipse you can simply tell it to show all the references and even a call hierarchy of a method. Is there anything similar in Xcode? </p>
  
  <p>I know that Objective-C does not follow the same ways of identifying method signature as Java does (i.e. there is no method to a class, just a bunch of selectors mapped to an id at runtime), so i'm having a hard time trying to figure out how Xcode could even accomplish this.</p>
