Get user current location(lat/long) in all app state not always only when My app required without location manager delegate

Question

I am working on watch heart beat app and I want when user heart rate critical then we will get his current location in(foreground, background and terminate) and send it to our server. Is there any way through which I get user location only at that position. I don't want to update his location every time.

Answer 1

To get user location you have to declare :

let locationManager = CLLocationManager()

in your controller.

Then, in viewDidLoad you have to request for location and initialize the CLLocationManager get process :

// Ask for Authorisation from the User.
self.locationManager.requestAlwaysAuthorization() 

// For use in foreground
self.locationManager.requestWhenInUseAuthorization()

if CLLocationManager.locationServicesEnabled() {
    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
    locationManager.startUpdatingLocation()
}

You will get location in CLLocationManagerDelegate :

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    var location:CLLocationCoordinate2D = manager.location.coordinate
    print("locations = \(location.latitude) \(location.longitude)")
}

In your info.plist you have to add NSLocationAlwaysUsageDescription and custom alert message to show while requesting for location.
