Getting SSID of the connected wifi network in Xamarin.iOS, iOS 13

问题

After passing from iOS 12 to 13 I am no more able to get the SSID of the connected wifi network.

I tried the solution for iOS 13 proposed in this question but with no result.

My previous successful code for iOS 12 (moreover 'CaptiveNetwork' is deprecated now):

if (CaptiveNetwork.TryGetSupportedInterfaces(out string[] supportedInterfaces) == StatusCode.OK)
{
    foreach (var item in supportedInterfaces)
    {
        if (CaptiveNetwork.TryCopyCurrentNetworkInfo(item, out NSDictionary info) == StatusCode.OK)
        {
            var ssid = info[CaptiveNetwork.NetworkInfoKeySSID].ToString();
            return ssid;
        }
    }
}

Any suggestion?

回答1:

Updated for iOS 13: Apple announced that iOS 13, the CNCopyCurrentNetworkInfo API will no longer return valid Wi-Fi SSID and BSSID information.

If your app requires valid Wi-Fi SSID and BSSID information to function, you can do the following: · For accessory setup apps, use the NEHotSpotConfiguration API, which now has the option to pass a prefix of the SSID hotspot your app expects to connect to. · For other types of apps, use the CoreLocation API to request the user’s consent to access location information.

So, I updated the above solution in the following way:

Add this key to your info.plist:

 <key>NSLocationWhenInUseUsageDescription</key>
 <string>Your Description</string>

Use the CoreLocation API to request the user’s consent to access location information.

    private void GetLocationConsent()
{
    var manager = new CLLocationManager();
    manager.AuthorizationChanged += (sender, args) => {
        Console.WriteLine("Authorization changed to: {0}", args.Status);
    };
    if (UIDevice.CurrentDevice.CheckSystemVersion(8, 0))
        manager.RequestWhenInUseAuthorization();

}

Call the GetLocationConsent() function before calling the "CaptiveNetwork".
