Answer 1

You cannot turn location services on from your app if the user has switched them off. You can only check with

[CLLocationManager locationServicesEnabled]

whether the user has switched them off or not.

CLLocationManager does not have the interface that you show. For the real interface see the Class Reference. You can check that same reference to see how to use the various types of location services.
