An application can specify a location service authorization type to be enforced by a mobile device. After the user authorizes the location service through an authorization dialog, the application can receive location service according to the authorization type. A first authorization type allows the application to receive continuous location updates and location events from a location service on the mobile device only when the application is in use. A second authorization type allows the application to always receive continuous location updates and location events when the application is running in a foreground or background. The text of the authorization dialog can be customized by the application to provide more detail on how the location data will be used by the application.
