title: How to add a done button over the pickerview?
body: <p>I want to display a <strong>picker view and a done button</strong> above the picker view . 
          <br><br> I have a custom label which will become first responder . So when it becomes first responder I am displaying a picker view as the input view for my label. 
           Now I want to have a done button on the picker to dismiss the picker view. I played with the <strong>inputAccesoryView</strong> property of <strong>UIPickerView</strong> but did not succeed . inputAccessoryView is possible with <strong>UITextView</strong> , not sure about the <strong>UIPickerView</strong> . Here is the link for how it can be done with <strong>UITextView</strong></p>

  <p>Thank you all in advance !!</p>
