从Azure Notification Hub（Xamarin.ios）推送通知

Question

null

private SBNotificationHub Hub { get; set; }
    public const string ConnectionString = "Endpoint=sb://...";
    public const string NotificationHubPath = "NotificationHubName...";


     public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
            {
                // Set our preferred notification settings for the app
                var pushSettings = UIUserNotificationSettings.GetSettingsForTypes(
                    UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound,
                    new NSSet());

                // Register for notifications
                UIApplication.SharedApplication.RegisterUserNotificationSettings(pushSettings);
                UIApplication.SharedApplication.RegisterForRemoteNotifications();
                bool IsRegistered = UIApplication.SharedApplication.IsRegisteredForRemoteNotifications;

                return true;
            }
public override void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken)
        {
            Hub = new SBNotificationHub(ConnectionString, NotificationHubPath);
            Hub.UnregisterAllAsync(deviceToken, (error) =>
            {
                if (error != null)
                {
                    // Error unregistering
                    return;
                }
                // Register this device with the notification hub
                Hub.RegisterNativeAsync(deviceToken, null, (registerError) =>
                {
                    if (registerError != null)
                    {
                        // Error registering
                    }
                });
            });
        }

        public override void ReceivedRemoteNotification(UIApplication application, NSDictionary userInfo)
        {
            if (null != userInfo && userInfo.ContainsKey(new NSString("aps")))
            {
                // Get the aps dictionary from the alert payload
                NSDictionary aps = userInfo.ObjectForKey(new NSString("aps")) as NSDictionary;
            }
        }

我的问题是；

1. 我为什么不注册？
2. 如何了解为什么不注册？
3. Xamarin是否支持来自Azure notification Hub的iOS 11.0推送通知？

注意：我正在使用

• Windows 10上的Visual Studio 2017（15.4.0版）
• Mac OS高Siera版本10.13
• Xcode版本9.0.1
• VS for Mac Community V7.2（build 636)
• 测试iPhone 5s、iPhone 6、iPhone 6s、iPhone 7、iPhone 8-iOS11.0

Answer 1

通过使用物理iPhone设备解决了这个问题。

“模拟器不做推送通知。从服务器推送，你必须有设备（一个或多个）来推送，以及你在该设备上的应用程序。”

“iPhone模拟器无法接收推送通知，也无法为其成功注册。”
