title: UIAlertView enter Apple ID and Password IAP
body: <p>When I start test my IAP the system requests me apple id and password. There is an alert view with ok and cancel buttons.</p>
  
  <p>I need to handle this button, because when I press on cancel button I need to make some action  in app.</p>
  
  <p>Very important: there is an autorize dialog not a purchase alert. I need to know how to process this action in app (for example if user tap on cancel button and after this autorize dialog disappear)</p>
