I'm still trying to get the AGSMapView to work in my Tab View Controller (using Storyboard). I couldn't include a UIWindow in my main delegate class since it gets placed over my Tab View Controller. Is this required for AGSMapView? If not, is their some documentation available for using AGSMapView in a Tab View Controller? I'm using AGSMapViewLayerDelegate for my UIViewController but I still get a blank view on this particular tab.
