title: How to find out who called a method?
body: <p>Example: When my method -fooBar gets called, I want it to log in the console which other method of which other class called it.</p>
  
  <p>Right now, I only know how to log the method name of fooBar itself and it's class, with this:</p>
  
  <pre><code>_cmd
  
  [self class]
  </code></pre>
  
  <p>Is this possible to figure out?</p>
