Xamarin Forms Maps-在iOS上显示当前位置 [英] Xamarin Forms Maps - showing current location on iOS

问题描述

在Xamarin Forms中，Xamarin.Forms.Maps的IsShowingUser属性是否适用于iOS?

In Xamarin Forms, does the IsShowingUser property of Xamarin.Forms.Maps work for iOS?

我可以使地图的各个方面都可以在Android和iOS上使用，但是当前位置蓝点"在iOS上不显示.

I can get every aspect of my map to work on both Android and iOS, but the current location 'blue dot' does not show on iOS.

在成功请求使用位置的权限之后，我正在PCL项目的共享代码中进行设置.

I'm setting this in shared code in the PCL project, just after successfully asking for permission to use location.

var status = await CrossPermissions.Current.CheckPermissionStatusAsync(Permission.Location);
            if (status != PermissionStatus.Granted)
            {
                var results = await CrossPermissions.Current.RequestPermissionsAsync(new[] { Permission.Location });
                status = results[Permission.Location];
            }

            if (status == PermissionStatus.Granted)
            {
                MyMap.IsShowingUser = true;
            }

谢谢

这是因为当时地图未找到当前用户位置，因此可以使用 Xam.Plugin .Geolocator 获取您的当前位置，然后将地图移至该位置.

It is because the map doesn't locate the current user location at that time, you can use Xam.Plugin.Geolocator to get your current location, and move the map to it.

var locator = CrossGeolocator.Current;
var position = await locator.GetPositionAsync(TimeSpan.FromSeconds(10));
map.MoveToRegion(MapSpan.FromCenterAndRadius(new Position(position.Latitude, position.Longitude),
                                                     Distance.FromMiles(1)));
