title: Editing a Keyboard in iOS
body: <p>In terms of application for iOS coding, how can you manipulate the pre-existing keyboards? I want to change a button on the keyboard (for example, the A button on the English key board) to a custom image and custom output. </p>
  
  <p>So I guess what I'm asking is: if and how you can access a pre-existing keyboard and if you can change the output of one of the keyboard buttons to a custom image which others will see if you send it to them? </p>
