title: How to pass method arguments to a selector
body: <p>If I have a method like this:</p>
  
  <pre><code>- (void) foo
  {
  }
  </code></pre>
  
  <p>Then I can access it through a selector like this:</p>
  
  <pre><code>@selector(foo)
  </code></pre>
  
  <p>But what if I have a method like this:</p>
  
  <pre><code>- (void) bar:(NSString *)str arg2:(NSString *)str2
  {
  
  }
  </code></pre>
  
  <p>Then how do I access it through a selector?</p>
