title: 'Calling a method' OR 'sending a message' in Objective C
body: <p>In C or any ECMAscript based language you 'call a public method or function' on an object. But in documentation for Objective C, there are no public method calls, only the sending of messages.</p>
  
  <p>Is there anything wrong in thinking that when you 'send a message' in ObjC you are actually 'calling a public method on an Object'.?</p>
