有人问过这个问题before。但是我仍然不知道如何解决它。通知不起作用，我唯一的线索是：Failed to fetch APNS token Error Domain=com.firebase.iid Code=1001 "(null)"

我已经仔细检查了我是否将正确的 .p12 文件上传到了 firebase。我已进入目标->-> 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，如果没有最后两种方法，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()
}

我可以看到控制台上打印的 deviceToken。但我仍然遇到这个 FireBase 问题。我可以检查的其他内容有什么想法吗？

我确实尝试基于 Firebase/Quickstart-iOS 示例为 iOS (Swift) 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)"。

当应用程序在后台时，我无法收到通知。 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);
        }

...和这行代码：

application.registerForRemoteNotifications()

显然，用 Objective-C 编写的示例可以正常工作，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。否则尽量避免调用unregisterForRemoteNotifications。在此呼叫之后，您无法再注册设备以推送通知。另外，尝试在 info.plist 文件中将FirebaseAppDelegateProxyEnabled 设置为NO。我认为他们的方法混乱存在错误。

调用这个方法你会得到设备令牌。我可以看到控制台上打印的deviceToken。

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