此问题已被问及before。但我仍然不知道如何解决它。通知不起作用，我所拥有的唯一线索是：Failed to fetch APNS token Error Domain=com.firebase.iid Code=1001 "(null)"

我已经仔细检查过我将正确的.p12文件上传到firebase中。我已进入Target-＆gt; - ＆gt;功能 - ＆gt;背景模式 - ＆gt; remote-notifications和ON 我已经仔细检查过我的bundleID与GoogleService-Info.plist匹配

这是我的AppDelegate.swift

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.
        FIRApp.configure()
        ....
}

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    print("DEVICE TOKEN = \(deviceToken)")
    FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Sandbox)
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
                 fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
    // If you are receiving a notification message while your app is in the background,
    // this callback will not be fired till the user taps on the notification launching the application.
    // TODO: Handle data of notification
    FIRMessaging.messaging().appDidReceiveMessage(userInfo)

    // Print message ID.
    print("Message ID: \(userInfo["gcm.message_id"]!)")

    // Print full message.
    print("%@", userInfo)
}
func tokenRefreshNotification(notification: NSNotification) {
    // NOTE: It can be nil here
    let refreshedToken = FIRInstanceID.instanceID().token()
    print("InstanceID token: \(refreshedToken)")

    connectToFcm()
}

func connectToFcm() {
    FIRMessaging.messaging().connectWithCompletion { (error) in
        if (error != nil) {
            print("Unable to connect with FCM. \(error)")
        } else {
            print("Connected to FCM.")
        }
    }
}

我的猜测是它应该可以在没有最后两种方法的情况下工作，但无论如何我都把它们放在那里（根据印刷语句，它看起来不像是被调用）。

我调用registerForRemoteNotifications：

static func registerForNoties(){

    let notificationTypes: UIUserNotificationType = [UIUserNotificationType.Alert, UIUserNotificationType.Badge, UIUserNotificationType.Sound]
    let pushNotificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil)
    UIApplication.sharedApplication().registerUserNotificationSettings(pushNotificationSettings)
    UIApplication.sharedApplication().registerForRemoteNotifications()
}

我可以在控制台上看到deviceToken。但我仍然遇到这个FireBase问题。我可以检查其他任何想法吗？

我确实尝试构建基于适用于iOS（Swift）的Firebase / Quickstart-iOS示例的简单应用，我遇到了同样的问题：Failed to fetch APNS token Error Domain=com.firebase.iid Code=1001 "(null)"。

当app在后台时，我无法收到通知。所以，我找到了适合我的解决方案： https://github.com/firebase/quickstart-ios/issues/103

基本上，我确实添加了这个方法：

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
            print("Handle push from background or closed" );
            print("%@", response.notification.request.content.userInfo);
        }

......以及这行代码：

application.registerForRemoteNotifications()

显然，使用Objective-C编写的示例工作正常，但Swift中的示例缺少一些代码，并且无法按预期工作...

尝试将Firebase / Core更新到v3.4.4，它为我修复了意外错误。否则请尽量避免调用390px。此调用后，您无法再注册设备以推送通知。另外，尝试在info.plist文件中将unregisterForRemoteNotifications设置为FirebaseAppDelegateProxyEnabled。我认为他们的方法有很多错误。

调用此方法您将获得设备令牌。我可以在控制台上看到deviceToken。

dispatch_async(dispatch_get_main_queue(),
{
     global.appdel.tokenRefreshNotification()
})

Firebase无法获取APNS令牌错误域= com.firebase.iid代码= 1001＆＃34;（null）＆＃34;
