title: UITextField clear when selected, but also restore data if nothing is input
body: <p>I have a table with UITextFields, and I want to make it so that when a textfield is selected, the current info is cleared (to allow new input), but if the user decides (after selecting) that they don't want to change it, I want them to be able to click elsewhere and the data from before reappears in the textfield.</p>
  
  <p>Is there an easy way to do this?</p>
