I am implementing ads with adMob SDK, mediating adMob and iAd.I want to implement a Singleton banner in my iOS app game that'll have 1 ad playing on all ViewControllers and when iAd fails, AdMob fills. However, my app does not using UINavigationController or UITabView. I just use storyboards. There are a few guides for Singleton class iAd/AdMob mediation but they're for UINavigationController and/or UITabView.
1) Is the only way to implement Singleton class banner in Xcode for iOS app through UINavigationController and/or UITableView?
2) If I can use Singleton class for iAd/AdMob mediation, is there a guide or a starting point somewhere because I really don't know where to start. Any help would be appreciated.
