Firebase无法获取Code=1001令牌错误Domain=com.firebase.iid APNS“(空)”

这个问题已经被问到了before。但我仍然对如何修复它感到困惑。通知不起作用，我唯一的线索就是这行：Failed to fetch APNS token Error Domain=com.firebase.iid Code=1001 "(null)"

我已经仔细检查过我是否上传了正确的.p12文件到firebase中。我已经进入了目标->功能->后台模式->remote-notifications和ON我已经仔细检查了我的bundleID是否与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，没有最后两个方法，它应该可以工作，但我还是把它们放在那里(根据print语句，它看起来不像是被调用的)。

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打印的deviceToken。但是我仍然有这个FireBase的问题。还有其他的想法我可以检查一下吗？

我确实尝试过基于iOS的Firebase/Quickstart-iOS示例构建简单的应用程序，但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，我无法接收通知。所以，我在这里找到了适合我的解决方案：https://github.com/firebase/quickstart-ios/issues/103

基本上，我添加了这个方法：

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

..。下面这行代码：

application.registerForRemoteNotifications()

显然，用Objective-C编写的example运行良好，但Swift中的example缺少一些代码片段，并且不能像预期的那样工作。

尝试将Firebase/Core更新到v3.4.4，它为我修复了意外错误。否则，尽量避免调用unregisterForRemoteNotifications。在此调用之后，您将无法再注册设备以推送通知。另外，尝试在info.plist文件中将FirebaseAppDelegateProxyEnabled设置为NO。我认为他们的方法有缺陷。

调用此方法，您将获得设备令牌。我可以在控制台上看到打印的deviceToken。

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