Xamarin Forms: How to check if GPS is on or off in Xamarin ios app?

Question

Whenever I am opening my app I need to check the GPS is on or off. If the GPS is off, I need to redirect the user to the location settings page. I have done the android part using the dependency service like below.

ILocSettings

public interface ILocSettings
{
    void OpenSettings();

    bool isGpsAvailable();
}

Android implementation

[assembly: Dependency(typeof(LocationShare))]
namespace Projectname.Droid.Services 
{
    public class LocationShare : ILocSettings
    {
        public bool isGpsAvailable()
        {
            bool value = false;
            Android.Locations.LocationManager manager = (Android.Locations.LocationManager)Android.App.Application.Context.GetSystemService(Android.Content.Context.LocationService);
            if (!manager.IsProviderEnabled(Android.Locations.LocationManager.GpsProvider))
            {
                //gps disable
                value = false;
            }
            else
            {
                //Gps enable
                value = true;
            }
            return value;
        }

        public void OpenSettings()
        {
            Intent intent = new Android.Content.Intent(Android.Provider.Settings.ActionLocat‌​ionSourceSettings);
            intent.AddFlags(ActivityFlags.NewTask);
            Android.App.Application.Context.StartActivity(intent);
        }
    }
}

Finally from the shared project called like below:

//For checking the GPS Status
bool gpsStatus = DependencyService.Get<ILocSettings>().isGpsAvailable();
//For opening the location settings 
DependencyService.Get<ILocSettings>().OpenSettings();

For ios how I can I do the same features? I tried like below:

[assembly: Dependency(typeof(LocationShare))]
namespace Projectname.iOS.Serivces
{
    class LocationShare : ILocSettings
    {
        public bool isGpsAvailable()
        {
            //how to check the GPS is on or off here
        }

        public void OpenSettings()
        {
            UIApplication.SharedApplication.OpenUrl(new NSUrl(UIApplication.OpenSettingsUrlString));
        }
    }
}

Location settings page opening on ios simulators, but don't know how to check the GPS status.

Hello,​

Welcome to our Microsoft Q&A platform!

To check if the location service is enabled on iOS , try using the CLLocationManager.LocationServicesEnabled method.

   bool status = CLLocationManager.LocationServicesEnabled;  
   //check the status's value
