xamarin表示允许使用位置iOS

Question

我正在使用Xamarin.Forms并创建一个拥有后台服务的iOS应用程序,每10分钟获取一个位置.

代码正常,我的问题是当我在IPad上访问App配置时.它显示访问摄像机但不访问当前位置的权限.

我认为,当我提交应用程序进行审核时,这将是一个问题.

用于初始化位置:

this.locMgr = new CLLocationManager();
if (UIDevice.CurrentDevice.CheckSystemVersion(8, 0))
{
    locMgr.RequestAlwaysAuthorization(); // works in background
    //locMgr.RequestWhenInUseAuthorization (); // only in foreground
}

获取位置:

if (CLLocationManager.LocationServicesEnabled) 
{
    if (CLLocationManager.Status==CLAuthorizationStatus.Authorized 
     || CLLocationManager.Status==CLAuthorizationStatus.AuthorizedAlways)
    {
        //set the desired accuracy, in meters
        LocMgr.DesiredAccuracy = 1;
        LocMgr.LocationsUpdated += (object sender, CLLocationsUpdatedEventArgs e) =>
        {
            _currentLocation = (e.Locations[e.Locations.Length - 1]);
        };

        LocMgr.AuthorizationChanged += (object sender, CLAuthorizationChangedEventArgs e) =>
        {
            if (e.Status == CLAuthorizationStatus.Denied 
             || e.Status == CLAuthorizationStatus.Restricted)
            {
                LocMgr.StopUpdatingLocation();
                _currentLocation = null;
            }
        };

        LocMgr.StartUpdatingLocation();
    }
}

我忘记了什么？

您是否将这些密钥添加到Info.plist文件中？

<key>NSLocationAlwaysUsageDescription</key>
<string>Your message goes here</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>Your message goes here</string>
