title: Dismiss keyboard in custom keyboard ios8 not working
body: <p>I'm having some trouble with the custom keyboard extension in ios8 with the dismiss keyboard method.</p>
  
  <p>I'm calling it with : </p>
  
  <pre><code>[self dismissKeyboard];
  </code></pre>
  
  <p>It compiles OK, but when I press my dismiss button it crashes and open the normal keyboard. In the console I can only see the next few lines:</p>
  
  <blockquote>

  <p>I'm using ios 8 beta 6 and running it into the emulator. The same happens in the device with the lastest beta (ios5)</p>
