iPhone UIKeyboardTypeNamePhonePad with shift key
<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 shift key is disabled. Is there a way to enable the shift-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 shift key is missing.</p>

<p>Thanks for hints.</p>
