title: Presenting just a subset of emojis on the keyboard on iOS apps
body: <p>I am making an app where I use the "People" emojis as avatar faces and the "Food and drink" emojis for, well, food and drink icons. I would like to use the regular keyboard for presenting the emojis for user input, but I would like to present only these two categories of emojis (and even so, each category would be presented in a different context).</p>
  
  <p>I am working with iOS 8, Xcode 6.3 and Swift.</p>
  
  <p>Can I configure the regular keyboard so that it only shows a subset of emojis which I define?</p>
  
  <p>If not, can I create a new custom keyboard preserving everything from the original Apple keyboard but limiting the subset of characters? Any pointers on how to do this?</p>
  
  <p>Thanks.</p>
