title: How to disable UITextField editing but still accept touch?
body: <p>I'm making a <code>UITextField</code> that has a <code>UIPickerView</code> as <code>inputView</code>. Its all good, except that I can edit by copy, paste, cut and select text, and I don't want it. Only the Picker should modify text field.</p>
  
  <p>I've learned that I can disable editing by setting <code>setEnabled</code> or <code>setUserInteractionEnabled</code> to <code>NO</code>. Ok, but the TextField stop responding to touching and the picker don't show up.</p>
  
  <p>What can I do to achieve it?</p>
