IAds showing Ad error was unloaded from this banner when switching between tabs in UITabBarController

I'm rooting iAds in your app for the first time, and the application itself - it's a simple 5-loose UITabBarController, where the first 4 are tabs UIViewControllerwith UITableViewa built-in, and the last tab - UITableViewController.

Following this guide: http://www.appcoda.com/ios-iad-introduction/ I have successfully implemented iAds, and it appears in the application and works through each delegate method.

I made the first 4 tabs have iAds, but the last tab does not work. This is because the last tab is static UITableView, and I cannot insert it in UIViewController, etc. So, the first 4 tabs have adBannerView. adBannerViewis added from Storyboardto this UIViewController.

Question

During development on a real device running iOS 8.1.1 (and on another device with 8.2), when I am on the first tab, it shows the iAd banner without any problems. When I switch to the second tab and return to the first tab, two things happen:

1) adBannerViewis, but the actual ad itself is displayed for a second, and then disappears again. 2) The delegate method below throws an error as soon as I leave the first tab:

- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
{
    NSLog(@"Unable to show ads. Error: %@", [error localizedDescription]);
}
NSLog: Unable to show ads. Error: The operation couldn’t be completed. Ad was unloaded from this banner.
