didReceiveRemoteNotification无法正常工作

问题描述

import UIKit
import Firebase
import FirebaseInstanceID
import FirebaseMessaging

class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

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

        FIRApp.configure()

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

        // Add observer for InstanceID token refresh callback.
        NSNotificationCenter
            .defaultCenter()
            .addObserver(self, selector: #selector(AppDelegate.tokenRefreshNotificaiton),
                         name: kFIRInstanceIDTokenRefreshNotification, object: nil)

        return true
    }

    func applicationDidEnterBackground(application: UIApplication) {


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

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

    func applicationDidBecomeActive(application: UIApplication) {
        connectToFcm()
        // 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.
    }

    func applicationWillTerminate(application: UIApplication) {
        // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
    }

    func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
                     fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {

        FIRMessaging.messaging().appDidReceiveMessage(userInfo)
        print("Message ID: \(userInfo["gcm.message_id"]!)")

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


    func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
        print(error)
    }
    func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {

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


    func tokenRefreshNotificaiton(notification: NSNotification) {
        guard let refreshedToken = FIRInstanceID.instanceID().token()
            else {
                return
        }
        //refreshedToken = FIRInstanceID.instanceID().token()!
        print("InstanceID token: \(refreshedToken)")

        utill.tokenDefault.setValue(refreshedToken, forKey: "tokenId")
        // Connect to FCM since connection may have failed when attempted before having a token.
        connectToFcm()
    }


    func connectToFcm() {
        FIRMessaging.messaging().connectWithCompletion { (error) in
            if (error != nil) {
                print("Unable to connect with FCM. \(error)")
            } else {
                print("Connected to FCM.")
            }
        }
    } 
}

如果我们直接从Firebase帐户发送消息，则将推播通知发送到其他设备，甚至弹出通知都可以正常工作.但是didReceiveRemoteNotification在接收通知时没有被呼叫.

Everything works fine with sending push notification to other device and even popup notification coming if we send message directly from Firebase account. But didReceiveRemoteNotification is not getting called while receiving notification.

推荐答案

尝试一下:

func userNotificationCenter(_ center: UNUserNotificationCenter,  willPresent notification: UNNotification, withCompletionHandler   completionHandler: @escaping (_ options:   UNNotificationPresentationOptions) -> Void) {
    print("Handle push from foreground")
    // custom code to handle push while app is in the foreground
    print("\(notification.request.content.userInfo)")
 }

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    print("Handle push from background or closed")
    // if you set a member variable in didReceiveRemoteNotification, you  will know if this is from closed or background
    print("\(response.notification.request.content.userInfo)")
}

将此代码添加到您的应用程序委托之前，必须在应用程序中添加两个通知框架.

Add this code to your app delegates before that you have to add two notification framework in your application.
