位置服务在 iOS 8中无法使用

Question

My app that worked fine on iOS 7 doesn't work with the iOS 8 SDK.

CLLocationManager doesn't return a location, and I don't see my app under Settings -> Location Services either. I did a Google search on the issue, but nothing came up. What could be wrong?

Answer 1

I ended up solving my own problem.

Apparently in iOS 8 SDK, requestAlwaysAuthorization (for background location) or requestWhenInUseAuthorization (location only when foreground) call on CLLocationManager is needed before starting location updates.

There also needs to be NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription key in Info.plist with a message to be displayed in the prompt. Adding these solved my problem.

Hope it helps someone else.
