OS X save location permission - swift

Question

I'm getting the users GPS Location like this:
var manager:CLLocationManager!
override func viewDidLoad() {
super.viewDidLoad()
manager = CLLocationManager()
manager.delegate = self
manager.desiredAccuracy = kCLLocationAccuracyBest
manager.startUpdatingLocation()
//manager.requestAlwaysAuthorization()
//manager.requestWhenInUseAuthorization()
}
func locationManager(manager:CLLocationManager, didUpdateLocations locations: [AnyObject]) { // Updated to current array syntax [AnyObject] rather than AnyObject[]
println("locations = \(locations)")
}
The commented-out functions seem not to exist for os x applications. It still works for me so that's fine.
But every time I run the code it asks for permission to use location.
Is it possible to store the permission somewhere, so it only asks on the first execution?

Answer 1

Quoting Apple's documentation:
Call the authorizationStatus class method to get the current authorization status for your app.
If the authorization status is kCLAuthorizationStatusRestricted or kCLAuthorizationStatusDenied, your app is not permitted to use location services and you should abort your attempt to use them.
Your code on OS X should look like this:
override func viewDidLoad() {
super.viewDidLoad()
let status = CLLocationManager.authorizationStatus()
if status == .Restricted || status == .Denied {
// User permission not given
return
}
manager = CLLocationManager()
manager.delegate = self
manager.desiredAccuracy = kCLLocationAccuracyBest
manager.startUpdatingLocation()
}
Permission is managed centrally by Mac OS X. The first time you call startUpdatingLocation, it will ask for permission then remembers what the user has decided.
