ios8 - iOS 8 Location services in MapBox

I'm using MakBox for iOS 1.4.1 SDK in my iPhone app with Objective C.
In updating my app for XCode 6 and iOS 8 I added the NSLocationWhenInUseUsageDescription item to my plist settings. I tested and did not receive any location updates. I then added the NSLocationAlwaysUsageDescription key and that enabled updates to "flow". My question is: Since I don't need location services when the app isn't running I'd like to just use the WhenInUse permission but MapBox doesn't appear to work. So, if forced to use AlwaysUsage Apple throws the scary waring permission question about the app using location services even when the app is running.

Am I missing something here?

Edit - My location updates come from my RMMapViewDelegate methods. If I use the NSLocationAlwaysUsageDescription and the user allows always permission I get the updates. If I use the NSLocationWhenInUseUsageDescription I get nothing.
Edit - I added CLLocationManagerDelegate to my VC and properly spelled NSLocationWhenInUseUsageDescription and if I call [self.locationManager requestWhenInUseAuthorization] I will get the prompt and WhenInUse location updates will work.
