Question

I want to know can we turn on/off the GPS programmatically in iPhone?

Answer 1

Previous to iOS 5 the behavior was not consistent for launch of phone setting from third party application, but in iOS5 this is improved.

If we are calling startUpdatingLoaction method as below code and if location service is off,the system alert will popup and if we tap setting button,it will navigate to phone setting.

CLLocationManager *locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
[locationManager startUpdatingLocation];
