APNS Firebase通知无法获取令牌

问题描述

ios10-swift-3-and-firebase-push-notifications-fcm> ios10，Swift 3和Firebase推送通知（FCM）

试图使用Firebase for Notifications，我完全按照文档中的描述进行了整合。
但我不明白为什么不行。当我建立我的项目，我看到这一行：

  2016-05-25 16：09：34.987：< FIRInstanceID / WARNING> ;无法获取默认标记Error Domain = com.firebase.iid Code = 0（null）
  

我的AppDelegate：
$ b $ pre $ func application（application：UIApplication，didFinishLaunchingWithOptions launchOptions：[NSObject：AnyObject]？） - > Bool {
FIRApp.configure（）
FIRDatabase.database（）。persistenceEnabled = true
var service：DataService = DataService（）
service.start（）
registerForPushNotifications （application）
application.registerForRemoteNotifications（）
return true

$ b func registerForPushNotifications（application：UIApplication）{
let notificationSettings = UIUserNotificationSettings（
forTypes：[.Badge，.Sound，.Alert]，categories：nil）
application.registerUserNotificationSettings（notificationSettings）
}

func应用程序（application：UIApplication，didRegisterUserNotificationSettings notificationSettings：UIUserNotificationSettings）{$ b $如果notificationSettings.types！= .None {
application.registerForRemoteNotifications（）
}
}

func application（application： UIApplication，didRegisterForRemoteNotificationsWithDeviceToken deviceToken：NSData）{
let tokenChars = UnsafePointer< CChar>（deviceToken.bytes）
var tokenString =

for i in 0 ..< deviceToken.length {
tokenString + = String（format ：％02.2hhx，参数：[tokenChars [i]]）
}

FIRInstanceID.instanceID（）。setAPNSToken（deviceToken，type：FIRInstanceIDAPNSTokenType.Unknown）
print （Device Token：，tokenString）
}
func application（application：UIApplication，didReceiveRemoteNotification userInfo：[NSObject：AnyObject]，fetchCompletionHandler completionHandler：（UIBackgroundFetchResult） - >无效）{
//打印消息ID。
print（Message ID：\（userInfo [gcm.message_id]！））

//打印完整的信息。
print（％@，userInfo）
}


解决方案1.在 didFinishLaunchingWithOptions 方法中设置通知观察器

2.并设置 tokenRefreshNotification 方法那么你得到这个方法的令牌。

见下面的代码

 导入Firebase 
导入FirebaseMessaging 
 
覆盖func应用程序（应用程序：UIApplication，didFinishLaunchingWithOptions launchOptions：[NSObject：AnyObject]？） - > Bool {
 FIRApp.configure（）
 
 NotificationCenter.default.addObserver（self，
 selector：#selector（self.tokenRefreshNotification（notification :)），
 name ：NSNotification.Name.firInstanceIDTokenRefresh，
 object：nil）
} 
 
 //注意：当禁用swizzling时需要使用
 public func application（application： UIApplication，didRegisterForRemoteNotificationsWithDeviceToken deviceToken：NSData）{
 
 FIRInstanceID.instanceID（）。setAPNSToken（deviceToken，type：FIRInstanceIDAPNSTokenType.Sandbox）
} 
 
 func tokenRefreshNotification（notification： NSNotification）{
 //注意：在这里可以为零
 let refreshedToken = FIRInstanceID.instanceID（）。token（）
 print（InstanceID token：\（refreshedToken））
 
 connectToFcm（）
} 
 
 func conn ectToFcm（）{
 FIRMessaging.messaging（）。connectWithCompletion {（error）in 
 if（error！= nil）{
 print（无法连接FCM。 \（error））
} else {
 print（Connected to FCM。）
} 
} 
} 
 
 public func application（application：UIApplication，didReceiveRemoteNotification userInfo：[NSObject：AnyObject]）{$ b $ print（userInfo）
} 
  

For Swift3 / iOS10 see this link:

ios10, Swift 3 and Firebase Push Notifications (FCM)

I'm trying to use the Firebase for Notifications and I integrated it exactly as described in the docs.But I don't understand why is doesn't work. When I build my project I see this line:

2016-05-25 16:09:34.987: <FIRInstanceID/WARNING> Failed to fetch default token Error Domain=com.firebase.iid Code=0 "(null)"

This my AppDelegate:

 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    FIRApp.configure()
    FIRDatabase.database().persistenceEnabled = true
     var service: DataService = DataService()
    service.start()
    registerForPushNotifications(application)
    application.registerForRemoteNotifications()
    return true
}

func registerForPushNotifications(application: UIApplication) {
    let notificationSettings = UIUserNotificationSettings(
        forTypes: [.Badge, .Sound, .Alert], categories: nil)
    application.registerUserNotificationSettings(notificationSettings)
}

func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {
    if notificationSettings.types != .None {
        application.registerForRemoteNotifications()
    }
}

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    let tokenChars = UnsafePointer<CChar>(deviceToken.bytes)
    var tokenString = ""

    for i in 0..<deviceToken.length {
        tokenString += String(format: "%02.2hhx", arguments: [tokenChars[i]])
    }

    FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Unknown)
    print("Device Token:", tokenString)
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void)  {
    // Print message ID.
    print("Message ID: \(userInfo["gcm.message_id"]!)")

    // Print full message.
    print("%@", userInfo)
}

解决方案

1.Set Notification Observer in didFinishLaunchingWithOptions Method

2.And Set tokenRefreshNotification method then u get Token in this method.

See below Code

import Firebase
import FirebaseMessaging

override func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
  FIRApp.configure()

      NotificationCenter.default.addObserver(self,
                                                     selector: #selector(self.tokenRefreshNotification(notification:)),
                                                     name: NSNotification.Name.firInstanceIDTokenRefresh,
                                                     object: nil)
}

// NOTE: Need to use this when swizzling is disabled
public func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {

  FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Sandbox)
}

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.")
    }
  }
}

public func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
  print(userInfo)
}
