我正在尝试使用本教程向我的 Xamarin.iOS 应用程序添加推送通知 https://learn.microsoft.com/en-us/azure/notification-hubs/xamarin-notification-hubs-ios-push-notification-apns-get-started
我已按照原样执行了所有步骤,以下是我迄今为止尝试过的:-
AppDelegate.cs
public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
{
// create a new window instance based on the screen size
Window = new UIWindow(UIScreen.MainScreen.Bounds);
if (UIDevice.CurrentDevice.CheckSystemVersion(8, 0))
{
var pushSettings = UIUserNotificationSettings.GetSettingsForTypes(
UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound,
new NSSet());
UIApplication.SharedApplication.RegisterUserNotificationSettings(pushSettings);
UIApplication.SharedApplication.RegisterForRemoteNotifications();
}
else {
UIRemoteNotificationType notificationTypes = UIRemoteNotificationType.Alert | UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound;
UIApplication.SharedApplication.RegisterForRemoteNotificationTypes(notificationTypes);
}
// If you have defined a root view controller, set it here:
UIStoryboard storyboard = UIStoryboard.FromName("Main", null);
var myViewController = storyboard.InstantiateViewController("Login_VC") as LoginViewController;
Window.RootViewController = myViewController;
// make the window visible
Window.MakeKeyAndVisible();
return true;
}
public override void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken)
{
Hub = new SBNotificationHub(ServiceConstants.ListenConnectionString, ServiceConstants.NotificationHubName);
string token = deviceToken.ToString().Replace("<", "").Replace(">", "").Replace(" ", "");
deviceToken = NSData.FromString(token);
Hub.UnregisterAllAsync(deviceToken, (error) =>
{
if (error != null)
{
Console.WriteLine("Error calling Unregister: {0}", error.ToString());
return;
}
NSSet tags = null; // create tags if you want
Hub.RegisterNativeAsync(deviceToken, tags, (errorCallback) =>
{
if (errorCallback != null)
Console.WriteLine("RegisterNativeAsync error: " + errorCallback.ToString());
});
});
}
我已使用 Apple 开发者控制台中的开发配置文件对我的应用程序进行了签名,该配置文件是使用启用了推送通知的 AppId 进行签名的。
但是当我在注册推送通知时一开始就遇到错误,如下所示:-
Error Response:<Error><Code>401</Code><Detail>ExpiredToken: .TrackingId:94e8c47b-1221-4188-8a75-9b744e12c9d7_G4,TimeStamp:1/20/2017 10:05:51 AM</Detail></Error>
Fail to perform registration operation.

}
我能够从 Xamarin.Android 的同一个通知中心获取推送通知,但不能从 Xamarin.iOS 获取推送通知。
如有任何帮助,我们将不胜感激。
最佳答案
回答我自己的问题,因为它可能对寻找类似内容的人有用。事实证明,我的设备上禁用了自动日期时间,因此设备 token 获取为无效或已过期,因为设备上的时间滞后了 30 分钟。
