How To Turn Location Service On

问题

How can I turn Location Services back on from the actual app when someone declined the first time. I have an option to turn it off or on.

回答1:

You can only prompt them to the screen to turn on location services like so:

[[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"prefs:root=LOCATION_SERVICES"]];
