Eine Warnung in Swift 3 erhalten, während Push Notification mit Firebase verwendet wird?

Question

Ich verwende den Push-Benachrichtigungsdienst für meine Demo-App. Mit Firebase kann ich die Benachrichtigungen an das Gerät senden. Aber einige Warnungen kommen in meiner Log-Nachricht. Wie kann ich es entfernen? Und eine andere Sache, wie kann ich das Gerät Token hier mit der aktualisierten Xcode 8 in Swift 3.

AppDelegate Codes erhalten:

import UIKit 
    import Firebase 
    import UserNotifications 
    import FirebaseInstanceID 
    import FirebaseMessaging 

    @UIApplicationMain 
    class AppDelegate: UIResponder, UIApplicationDelegate { 

var window: UIWindow? 


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



    UINavigationBar.appearance().barTintColor = UIColor(red: 233.0/255.0, green: 86.0/255.0, blue: 53.0/255.0, alpha: 1.0) 

    UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName : UIColor.whiteColor()] 
    UIBarButtonItem.appearance().tintColor = UIColor.whiteColor() 


    UITabBar.appearance().backgroundColor = UIColor.whiteColor() 
    // UITabBar.appearance().tintColor = UIColor.orangeColor() 
    UITabBar.appearance().tintColor = UIColor(red: 233.0/255.0, green: 86.0/255.0, blue: 53.0/255.0, alpha: 1.0)

Answer 1

1. erster dieses Observer hinzufügen in didFinishLaunchingWithOptions

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

2. Dann diese Add-Methode in Appdelegate.M Klasse

func tokenRefreshNotification(notification: NSNotification) { 

    let refreshedToken = FIRInstanceID.instanceID().token() 
    print("InstanceID token: \(refreshedToken)") 
    print("InstanceID token: \(notification.Object)") 


    connectToFcm() 
} 

3. prüfen Sie, ob diese Methode (tokenRefreshNotification) Wird aufgerufen oder nicht?

Bei dieser Methode u erhalten Token ID
