如何在Xamarin iOS App中启用位置服务

Question

I would like my simple to enable location services I have added the following in info.plist file

I have enabled background modes and location (ios Manifest Editor view)

However when i install the app (from XCode on a connected IPad - IPA). The app does popup a notification about allowing notifications however there is no message about enabling location services.

As per Ricardo's comment, I have added the required setting to my info.plist file. My info.plist file looks like this now.

The only popup i get after building, reinstalling the ipa is allow notifications and no popup to allow location services. What am i missing?

Answer 1

It only ask when you start using location. Alternatively you can force the app to prompt for user permission using Xamarin.Plugin.Permission package then check for permission and ask for it like this.

        var status = await CrossPermissions.Current.CheckPermissionStatusAsync(Permission.Location);
        if (status != PermissionStatus.Granted)
        {
            if(await CrossPermissions.Current.ShouldShowRequestPermissionRationaleAsync(Permission.Location))
            {
                await DisplayAlert("Need location", "Gunna need that location", "OK");
            }

            var results = await CrossPermissions.Current.RequestPermissionsAsync(Permission.Location);
            status = results[Permission.Location];
        }

NSLocationAlwaysUsageDescription is deprecated ( Source ),

Use NSLocationWhenInUseUsageDescription instead. Add this to your info.plist :

<key>NSLocationWhenInUseUsageDescription</key>
<string>Your Message</string>
