title: Background UIViewController loading when ModalViewController is in the foreground (iOS)
body: <p>I'm not sure why this is happening, but in the App delegate, I'm setting a viewcontroller as the root and presenting a ModalViewController in front of it. The strange thing is that the viewcontroller behind the modalviewcontroller is still loading even though it does not appear. Is this normal? Is there a way to prevent the viewcontroller behind the modalviewcontroller to load?</p>
  
  <p>Thank you</p>
