title: Add a done button to the top of the keyboard
body: <p>I am making a universal app that has a UITextView.
  When the app run on the iPad there is a button on the lower right which enables me to dismiss the keyboard.
  The iPhone version does not have such a button.
  I have seen on some iPhone apps a bar on top of the keyboard that has a done option.
  Is there an easy way to add an iPad style dismiss keyboard button to the iPhone app as well.
  If not, what is the best way to add a done style bar to the top of the keyboard?
  Thanks in advance.</p>
