Firebase 无法获取 APNS 令牌错误 domain=com.firebase.iid Code=1001 "(null)"

这个问题以前就有人问过。但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上传的。p12文件是否正确。我已经进入目标->->功能->背景模式-> remote-notifications和ON我已经仔细检查了我的bundleID是否匹配GoogleService-Info.plist

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，它应该没有最后两个方法，但我把它们放在那里(根据打印语句，它看起来不像他们正在被调用)。

我调用registerforremotenotifations:

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deviceToken打印在控制台上。但我还是遇到了FireBase的问题。还有什么我可以检查的吗?

我确实尝试构建基于Firebase/Quickstart-iOS的iOS (Swift)示例的简单应用程序，我有同样的问题: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);
        }

…这行代码:

application.registerForRemoteNotifications()

显然，在Objective-C中编写的示例工作得很好，但在Swift中的示例缺少一些代码片段，并且它不像预期的那样工作…

尝试更新Firebase/Core到v3.4.4，它为我修复了意想不到的错误。否则，尽量避免调用unregisterForRemoteNotifications。在这个调用之后，你不能再注册设备来推送通知了。此外，尝试在您的信息中将FirebaseAppDelegateProxyEnabled设置为NO。plist文件。我认为他们的方法swizzling有bug

调用此方法，您将获得设备令牌。我可以看到deviceToken打印在控制台上。

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