Firebase（FCM）无法获取APNS令牌Error Domain = com.firebase.iid Code = 1001
我正在尝试使用FCM进行通知。
但是<FIRInstanceID/WARNING>无法获取APNS令牌Error Domain=com.firebase.iid Code=1001 "(null)"发生，所以我无法获取通知。 有什么问题？
在控制台，
无法获取APNS令牌Error Domain=com.firebase.iid Code=1001 "(null)"
下面是我在Appdelegate代码
import UIKit import CoreData import Alamofire import Firebase import FirebaseInstanceID import FirebaseMessaging @UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate { var window: UIWindow? var badgeCount : Int = 0; 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) print("APNS: <\(deviceToken)>") } func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError){ print("Registration for remote notification failed with error: \(error.localizedDescription)") } func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]){ print("didReceiveRemoteNotification()") //if FirebaseAppDelegateProxyEnabled === NO: FIRMessaging.messaging().appDidReceiveMessage(userInfo) // handler(.NoData) } // [START refresh_token] func tokenRefreshNotification(notification: NSNotification) { print("tokenRefreshNotification()") if let token = FIRInstanceID.instanceID().token() { print("InstanceID token: \(token)") sendTokenToServer(token) FIRMessaging.messaging().subscribeToTopic("/topics/global") print("Subscribed to: /topics/global") } connectToFcm() } // [END refresh_token] func sendTokenToServer(currentToken: String) { print("sendTokenToServer() Token: \(currentToken)") // Send token to server ONLY IF NECESSARY } // [START connect_to_fcm] func connectToFcm() { FIRMessaging.messaging().connectWithCompletion { (error) in if error != nil { print("Unable to connect with FCM. \(error!)") } 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() }
- 如果我使用套件ID发送通知，我可以从Firebase套件收到通知。 但我不能得到如果我们的服务器发送通知到特定的设备与令牌。
对于我来说，我试图跟随thigs使其工作：
- 重新启用function – >推送通知，钥匙串共享和后台模式 – >远程通知
- 重新安装应用程序（这将生成新的刷新令牌，后续运行将相同，因此可能无法在每次运行应用程序时都打印）。
- 确保我有正确的.p12file upload到Firebase控制台 – >项目设置 – >云消息
- 在苹果开发人员中心重新检查configuration文件（我不得不重新激活ios开发人员configuration文件。）
您仍然可能会收到警告，但是如果您尝试使用刷新令牌从Firebase控制台发送通知，则会生效。
这听起来像你用来提供远程通知的服务器可能有你的FCM令牌的旧logging。 Google FCM文档声明可以在以下情况下旋转 （更改）FCM令牌：
- 该应用程序在一个新的设备上恢复
- 用户卸载/重新安装应用程序
- 用户清除应用程序数据。
他们引用了其良好的做法，使用委托callback方法来更新服务器的令牌logging：
func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) { // Send the token to your server here }
这种方法不适合我，所以我不得不在每次启动应用程序时手动更新（经过大约20-25秒的延迟，因为旋转不总是即时的）。 你可以这样做：
let token = Messaging.messaging().fcmToken // Send this to your server
这些更改后，我仍然得到警告控制台日志消息，但推送通知每次都完美。
