Answer 1

实现这个:

- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status {
    if (status == kCLAuthorizationStatusAuthorizedAlways || status == kCLAuthorizationStatusAuthorizedWhenInUse) {
        //allowed - do your logic
    }
    else if (status == kCLAuthorizationStatusDenied) {
        //denied
    }
}

Swift 2.2:

self.locationManager.requestAlwaysAuthorization()

Swift 3.0:

func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
    switch status {
    case .notDetermined:
        manager.requestAlwaysAuthorization()
    case .restricted, .denied:
        // location services unauthorized
    case .authorizedAlways, .authorizedWhenInUse:
        manager.startUpdatingLocation()
    @unknown default:
        print("New CLLocationManager.authorizationStatus() not handled!")
    }    
}

记得设置你的代表:

self.locationManager.delegate = self;

并由您的班级实现: locationManager
