title: centering a uipopover in iPad
body: <p>I would like to create a new keyboard for the iPad.</p>
  
  <p>I have designed a view that has the keys and all the underlying work to fill in a textbox as the user presses the keys, and passes the value back to the calling routine when the user presses the return button.   </p>
  
  <p>This all works ok.</p>
  
  <p>Now - I want to create this view as a popover.</p>
  
  <p>I have the basic operations complete (pops up and is dismissed)</p>
  
  <p>But now I need some fine tuning help.</p>
  
  <p>Here are my questions...  </p>
  
  <p>1) How do I create a popover window centered on the screen without a UIPopoverArrowDirectionAny selection?</p>
  
  <p>2) Ensure the popover window is the size that I created it with in the XIB file (currently, it resizes and removes some of the rightmost size of the window)</p>
  
  <p>Thanks<br>
