title: Why cant I see all available methods or properties present in a Class in XCode?
body: <p>I am noob to XCode and Obj-C world, so pardon me for my naive question.</p>
  
  <p>Following a tutorial, I was writing a basic program in Cocos2D that would accept touch input.<br>
  And one of the task was to add implement ccTouchBegan method, but that would not show up in XCode's code sense.<br>
  I wanted to implement this method<br>
  <code>-(BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event</code><br>
  but I would find only this one (related to touch began)<br>
  <code>-(BOOL) ccTouchesBeganWithEvent:(*)event</code>  </p>
  
  <p>Now that I a noob, how do I explore list of all available methods and properties for a particular Class?<img src="https://i.stack.imgur.com/7ycDo.png" alt="enter image description here"></p>
  
  <p>The image shows list of available methods that starts with ccT. ccTouchBegan and ccTouchEnded showed up because I have implemented them already. Else, they would not show just like ccTouchCancelled and ccTouchMoved events didn't show up.</p>
  
  <p>How do I see all available methods &amp; properties of a Class or Object?</p>
