title: iPad; TableView full of arbitrary number of text fields and buttons in different rows. resignFirstResponder on all textfields when button is pressed?
body: <p>iPad: </p>
  
  <p>I have a tableView full of an arbitrary number of text fields and buttons in different rows.  </p>
  
  <p>When you press a button I a modal popup will popup.  If you press a button while editing a text field (and the keyboard is displayed on the iPad) something hilarious will happen.  The popover will be 75% off the corner of the screen (with a quarter visible in quarter.)</p>
  
  <p>To avoid this bad behavior, how do you resignFirstResponder on all textfields in the table when the button is pressed?</p>
