title: Detecting Tab Key Press On Bluetooth Keyboard
body: <p>If a bluetooth keyboard is connected to an iPad, I can pick up the <strong>enter</strong> key with:</p>
  
  <pre><code>-(BOOL)textFieldShouldReturn:(UITextField *)textField
  </code></pre>
  
  <p>but what do I use if I need to detect the <strong>tab</strong> key as well?</p>
  
  <p>FYI using your hardware keyboard in the ios simulator is essentially the same thing.</p>
