You are right. I asked for iOS and got something talking about 10.6 - obviously OS X stuff. > > >> >> 2. Where am I "trying to start MapKit location updates" ?

But: authorizationStatus = kCLAuthorizationStatusNotDetermined locationServicesEnabled = YES so I do (as recommended): [ self.locationManager requestWhenInUseAuthorization ]; Now I would expect a panel to come up, asking the user "Do you want to allow this app to use Location Services?" But nothing is seen (iOS 8.0). And when I ask the manager for a location, I just get nil. Later on I get: locationManager:didChangeAuthorizationStatus: kCLAuthorizationStatusNotDetermined and: "Trying to start MapKit location updates without prompting for location authorization." Not very useful.
