Firebase（FCM）無法獲取APNS令牌Error Domain = com.firebase.iid代碼= 1001

Question

我正在嘗試使用FCM進行通知。
但<FIRInstanceID/WARNING>未能取得APNS令牌錯誤Domain=com.firebase.iid Code=1001 "(null)"發生，所以我無法獲取通知。 什麼問題？

在控制檯，
無法抓取APNS令牌Error Domain=com.firebase.iid Code=1001 "(null)"

以下是我對Appdelegate

import UIKit 
import CoreData

    var window: UIWindow?

    enum BasicValidity : String { 
     case Success = "basicInfo" 
     case Fail = "OauthAuthentificationError" 
    } 

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


     let uns: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil) 
     application.registerUserNotificationSettings(uns) 
     application.registerForRemoteNotifications() 

     FIRApp.configure() 

     NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.tokenRefreshNotification), name: kFIRInstanceIDTokenRefreshNotification, object: nil) 

     if let token = FIRInstanceID.instanceID().token() { 
      sendTokenToServer(token) 
      print("token is < \(token) >:") 
     } 

     return true 
    } 

    func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData){ 


     print("didRegisterForRemoteNotificationsWithDeviceToken()") 

     // if FirebaseAppDelegateProxyEnabled === NO: 
     FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: .Sandbox)

      } else { 
       print("Connected to FCM.") 
      } 
     } 
    } 
    // [END connect_to_fcm] 

    func applicationWillResignActive(application: UIApplication) { 
     // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state. 
     // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game. 
    } 

    // [START disconnect_from_fcm] 
    func applicationDidEnterBackground(application: UIApplication) { 
     // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later. 
     // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits. 

     FIRMessaging.messaging().disconnect() 
     print("Disconnected from FCM.") 
    } 

    func applicationWillEnterForeground(application: UIApplication) { 
     // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background. 
    } 

    func applicationDidBecomeActive(application: UIApplication) { 
     // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface. 

     // UIApplication.sharedApplication().applicationIconBadgeNumber = 0 
     connectToFcm() 

    } 

    func applicationWillTerminate(application: UIApplication) { 
     // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:. 
     // Saves changes in the application's managed object context before the application terminates. 
     self.saveContext() 
    } 

• 碼我可以從火力地堡康索爾得到通知，如果我用束髮的通知ID。但我不能得到如果我們的服務器發送通知到具有令牌的特定設備。

Answer 1

對於我來說，我嘗試以下thigs，使其工作：

• 重新啓用Capabilities->推送通知，鑰匙扣共享和背景modes->遠程通知
• 重新安裝應用程序（此將生成新的刷新標記，對於後續運行它將保持不變，所以每次運行應用程序時都不會打印）。
• 確保我在火力控制檯 - 上傳正確.p12文件>項目設置 - >雲消息
• 在複覈蘋果開發者中心的provisioning profile（我不得不重新激活的iOS開發者的provisioning profile）

您可能仍然會收到警告，但如果您嘗試使用刷新令牌從Firebase控制檯發送通知，則該操作將起作用。

聽起來像您用來提供遠程通知的服務器可能有您的FCM令牌的舊記錄。的谷歌FCM文檔狀態，所述FCM令牌可以旋轉（改變）時：

• 該應用新的設備
• 用戶卸載上還原/重新安裝該應用
• 用戶清除應用程序數據。

他們引用它的好習慣使用委託回調方法更新此令牌的服務器的記錄：

func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) { 
    // Send the token to your server here 
} 

這種方法並沒有爲我工作，所以我不得不手動的更新每次應用程序啓動（延遲20-25秒之後，因爲輪換並不總是即時的）。你可以這樣做：

let token = Messaging.messaging().fcmToken // Send this to your server 

這些變化我還是得到警告控制檯日誌消息後，但推送通知每次都很好地工作。
