title: How do I replicate the iOS keyboard appearance?
body: <p>I have made a custom number pad keypad for my iOS app, but want it to more closely mirror the appearance of the standard keyboard.  I am looking for advice on how to make a standard UIButton look and act like the standard keyboard buttons.</p>
  
  <p>Specifically, I need to figure out the following for the iPad and would like to do as much as possible in an xib or storyboard.</p>
  
  <ul>
  <li>The size of the buttons</li>
  <li>The color of the keyboard background (or even better, how can I determine this myself?)</li>
  <li>The background color of the button</li>
  <li>The font and color of the text in the button</li>
  <li>How do I add the shadow under the button?</li>
  <li>How do I have the button highlight with the grey color instead of blue?</li>
  <li>The spacing between the buttons</li>
  <li>How do I keep the "group" of buttons centered as a whole when changing the orientation?  (all of the resizing options anchor it to a side and not to each other)</li>
  </ul>
  
  <p>Do the standard buttons use images, or do they modify standard UIButton's?  Or more appropriately, which is better for us to do?</p>
  
  <p><strong>UPDATE:</strong><br>
  I have created a project for the number pad which is a complete working example.  However, I have not spent much time on the actual appearance, which is what this question was mainly about.  I have posted it on Github and made it an open source project (covered by the MIT licence, so commercial use is allowed as well).  Hopefully other people will find it useful, and hopefully others will feel inclined to help make it better and look more like the native keyboard.  The Github repository is at:</p>
