There are many apps in the locator service, and if the user turns off positioning, then we can prompt the user to open the location service in the app. Click to set interface settings, jump directly to the positioning Service settings interface. The code is as follows:

Copy Code code as follows:

Positioning Service Settings interface
Nsurl *url = [Nsurl urlwithstring:@ "prefs:root=location_services"];
