I've added peek and pop to my app which also has iAD banners.
The app has a table view and a detail view which is displayed when tapping on a cell. All fairly basic stuff. Each view has a banner ad at the bottom.
When navigating through the app normally, without 3D touch, the ads display normally. However, when I use 3D Touch to peek from a table cell, the iAd banner area turns black and any banner disappears. If I release at this point the area stays black and no banner is displayed. If I navigate normally into the detail page and back to the tableview the banners reappear.
When I pop into the detail view, the banner ad is initially displayed but almost immediately disappears never to return. This time, there is no black area left and the view content goes all the way to the bottom of the screen.
Any help gratefully received.
