title: iPhone UIKeyboardTypeNamePhonePad with shift key
body: <p>I have a UITextField for a username, and I set the keyboard type to:</p>
  
  <pre><code>uiUsername.keyboardType = UIKeyboardTypeNamePhonePad;
  </code></pre>
  
  <p>This way I can enter alphanumeric characters. But unfortunately the <kbd>Shift</kbd> key is disabled. Is there a way to enable the <kbd>Shift</kbd> key using this keyboard type?</p>
  
  <p>I know, I could set a different keyboard type and check for legal characters, but this keyboard type is very clean - only the <kbd>Shift</kbd> key is missing.</p>
  
  <p>Thanks for hints.</p>
