title: How do I call a method with multiple parameters
body: <p>hi I'm new to iOS development and i have a simple question.</p>
  
  <p>I don't know how to call the following method.</p>
  
  <pre><code>-(void) ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
    {
   //do something here
  
   }
  </code></pre>
  
  <p>But when I use </p>
  
  <pre><code>[self ccTouchesBegan]
  </code></pre>
  
  <p>I get an error and it doesn't work.
  I know this is really simple question but I can't figure it out by myself</p>
  
  <p>Thank you.</p>
