ios - 在 Xamarin iOS 中拒绝位置权限时应用程序崩溃

Question

我需要在我的应用程序中拥有位置信息，当用户通过单击“不允许”拒绝位置权限时，应用程序崩溃了。我得到“System.Reflection.TargetInvocableException”。但一旦我再次开始，即使在那个时候，权限被拒绝，它也不会崩溃。在android中它工作正常。我需要更新权限插件或更改info.Plist吗？这是我的代码

          var status = await CrossPermissions.Current.CheckPermissionStatusAsync(Permission.Location);
            if (status != PermissionStatus.Granted)
            {
                if (await CrossPermissions.Current.ShouldShowRequestPermissionRationaleAsync(Permission.Location))
                {
                    await Application.Current.MainPage.DisplayAlert("Location denied", "app needs access to location for this operation.", "OK");
                }

                var results = await CrossPermissions.Current.RequestPermissionsAsync(Permission.Location);
                status = results[Permission.Location];
            }
            if (status == PermissionStatus.Granted)
            {
                  // do something
            }
            else if (status != PermissionStatus.Unknown)
            {
                  // Crash when user denied permission 
            }

您应该在 Info.plist 中添加项目
