title: What is the typeof() equivalent in Objective-C?
body: <p>Is there a quick way to use some sort of typeof() equivalent in Objective-C? In Javascript I can type:</p>
  
  <pre><code>var a = "imastring";
  console.log(typeof(a));
  // --&gt; "string"
  </code></pre>
  
  <p>I would like something clean in Objective-C that isn't a compiler directive.</p>
