title: Objective-C passing parameters in void method
body: <p>How would I go about passing parameters when calling a void method? I understand that you can do something like this:</p>
  
  <pre><code>-(void)viewDidLoad {
      [self callMethod];
  }
  
  -(void)callMethod {
       //stuff here
  }
  </code></pre>
  
  <p>But how would I pass a parameter, such as an <code>NSString</code>, to the <code>callMethod</code> method?</p>
