title: Disable cursor and copy/paste in UITextView (swift)
body: <p>I have a <code>UITextField</code> for which I am using <code>UIPickerView</code> as its <code>inputView</code>. The user can select a value from the picker, and the selected value gets populated into my <code>TextInput</code>. 
  <br/>This arrangement works fine, but with the following issues:</p>
  
  <p>1) I want to disable the cursor that still shows in the <code>UITextField</code>. 
  <br/>I tried disabling the <code>UITextField</code>, but then it does not respond to touches and then the <code>UIPickerView</code> does not show - which makes it useless.<br/>
  2) Since the picker is shown and the keyboard is not wen the user taps on the text-field, the user cannot type anything, but still can paste text copied from else where by long pressing. How can I disable this?</p>
  
  <p>I am not able to find the relevant information online. Should I be using a <code>Label</code> or a <code>Button</code> for this instead of the <code>UITextInput</code>?</p>
