title: UITextfield keyboard with only alphabet, no numbers, no caps, no spacebar?
body: <p>I want the keyboard for the UITextfield to only have a-z, no numbers, no special characters (!@$!@$@!#), and no caps. Basicly I am going for a keyboard with only the alphabet.</p>
  
  <p>I was able to disable the space already. Anyone know how to disable numbers, special characters, and caps? A solution for any of these would be great.</p>
  
  <p>Is the best solution to do the below for all the characters but I dont want?</p>
  
  <pre><code>func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -&gt; Bool {
  
      if (string == " ") {
          return false
      }
  
      if (string == "1") {
          return false
      }
  
      return true
  }
  </code></pre>
