iAd banner shows empty black space after dismissing modal view

Question

My app shows banner ads at the bottom of UIViewController which is root view using self.canDisplayBannerAds = true in viewDidLoad(). App has a settings view which is a UITableViewController and i am showing the ads there as well in the same way.

When i dismiss the modal view (settings view/table view) the banner ads on root view UIViewController goes away and shows a black rectangular box where iAd banner is supposed to display.

The dismiss action/done button on modal view is a unwind to exit() segue.

I am suspecting it is something to do with modal presentation - over full screen or dismiss action i.e. unwind to exit() segue.

EDIT - Just to validate, I tried various presentation styles for modal view and segue back from settings scene to view scene and it worked. But doesn't work the way i am showing table view/settings page as modal view presentation over full screen

I did some more research but many posts suggest that reason behind as constraints/limitation of using iAd with UITableViewController

I could not identify any details about using iAd with UITableViewController so far. Need help and suggestions.

Move your self.canDisplayBannerAds = true to your viewDidAppear() for each view controller.
