title: How to dismiss modal view controller using UIAlertView?
body: <p>I'd like to dismiss the whole modal view controller by tapping cancel on the UIAlertView that I implemented. The alert view asks the user if he wants to logout and if the user taps Yes, it'll dismiss the modal view controller.</p>
  
  <p>How can I do this in Xcode?</p>
  
  <p>Thanks!</p>
