title: Getting the UIKeyboard background color programmatically
body: <p>Is there any way to get the <code>UIKeyboard</code> background color? I am putting an accessory view on top of my <code>UIKeyboard</code> and is trying to match its color with the keyboard background color. But, it seems, different types of keyboard has different background colors. Please see below screenshots for default and email keyboard.</p>
  
  <p>Is there any way, we can find out the background color of the keyboard programmatically so that the color of the <code>accessoryView</code> could be changed.</p>
