Get user’s current location Xamarin iOS - ios

Question

I am trying to get the location. I implement everything but nothing works.
This is my class:
public class Best2 : CLLocationManagerDelegate
{
public CLLocationManager _locationManager;
private Int32 _numEvento;
public Best2()
{
}
protected Best2(NSObjectFlag t) : base(t)
{
}
protected internal Best2(IntPtr handle) : base(handle)
{
}
public Best2(Int32 paramEvento)
{
_numEvento = paramEvento;
_locationManager = new CLLocationManager ();
_locationManager.PausesLocationUpdatesAutomatically = false;
_locationManager.DesiredAccuracy = CLLocation.AccurracyBestForNavigation;
if (UIDevice.CurrentDevice.CheckSystemVersion (9, 0)) {
_locationManager.AllowsBackgroundLocationUpdates = true;
}
_locationManager.Delegate = this;
StartLocationUpdates();
}
public void StartLocationUpdates ()
{
if (CLLocationManager.LocationServicesEnabled) {
_locationManager.RequestLocation();
System.Diagnostics.Debug.WriteLine(
String.Format(
"FA&)#2 RequestLocation() Data:D {0}"
, DateTime.UtcNow
)
);
}
}
public override void Failed (CLLocationManager manager, Foundation.NSError error)
{
System.Diagnostics.Debug.WriteLine(
String.Format(
"FA&)#2 Failed() Data:D {0}"
, DateTime.UtcNow
)
);
}
public override void UpdatedLocation (CLLocationManager manager, CLLocation newLocation, CLLocation oldLocation)
{
System.Diagnostics.Debug.WriteLine(
String.Format(
"FA&)#2 UpdatedLocation() Data:D {0}"
, DateTime.UtcNow
)
);
}
I call this way:
Best2 position = new Best2(1);
Based in the apple documentation, I think it should call the method Failed if not works and UpdatedLocation if works. But nothing is calling.
I already try to put the class receiving events, but it doesn't work either.

Answer 1

According to the documentation about Request Location we know that if we want to use location in iOS we must follow the steps below:
Add the NSLocationWhenInUseUsageDescription key and the NSLocationAlwaysAndWhenInUseUsageDescription key to your Info.plist file.
If your app supports iOS 10 and earlier, add the NSLocationAlwaysUsageDescription key to your Info.plist file.
Then before RequestLocation() we need to call RequestAlwaysAuthorization() or RequestWhenInUseAuthorization() to get user's authentication.
At last we can get the location but you misunderstand the event:
I think it should call the method Failed if not works and
UpdatedLocation if works.
If it works the event LocationsUpdated() will fire not UpdatedLocation().
