title: How to simulate a sign language keyboard in IOS?
body: <p>I'm trying to develop an app similar to this <a href="https://itunes.apple.com/us/app/sign-language-email-keyboard/id314603243?mt=8" rel="nofollow noreferrer">one</a> :</p>
  
  <p><img src="https://i.stack.imgur.com/mx5UP.jpg" alt="enter image description here"></p>
  
  <p>I was able to use custom font, but what if the letter are images and not a font file? Any how can I send it as an email for exemple? </p>
  
  <p>Thanks a lot.</p>
