Firebase when receive Push Notification did not receive the popup

问题

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

    registerForPushNotifications(application)
    FIRApp.configure()

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

    // Override point for customization after application launch.
    return true
  }

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


  func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
                   fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
    print("===== didReceiveRemoteNotification ===== %@", userInfo)
  }


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

    // 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.")
      }
    }
  }

Also to done in Info.plist FirebaseAppDelegateProxyEnabled = NO

I don't know for now but I got the print(...) in didReceiveRemoteNotification but don't get the popup. I send the message from Firebase -> Console -> Notification -> Single device and copy here the token which I got from xCode Console -> func tokenRefreshNotificaiton

Get the next in console, but don't get popup

<FIRAnalytics/INFO> Firebase Analytics enabled
InstanceID token: TOKEN_ID
Connected to FCM.
===== didReceiveRemoteNotification ===== %@ [notification: {
    body = test;
    e = 1;
}, collapse_key: com.pf.app, from: 178653764278]

Also app configurations

回答1:

set the following code in AppDelegate.m

   - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {

    // for development 
        [[FIRInstanceID instanceID] setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeSandbox];

    // for production 
   //     [[FIRInstanceID instanceID] setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeProd];


    }

回答2:

I'm guessing your app is in the foreground when testing. When your app is in the foreground no visible notification is triggered, instead you receive the callback to didReceiveRemoteNotification. See the documentation for more info.

To verify, put your app in the background and try sending the push notification again.

回答3:

I have same configuration you have and it works like AdamK said. (While in background mode, notification appears.) Also check your certificates.

回答4:

First check with Firebase Notification Console to see if the notification is sending or not. If it is success, then the problem is in the code side; otherwise, check what error is coming in Firebase. If you receive error message as APNs missing, you need to check with development/production .p12 file in Project Setting->Cloud Messaging tab.

回答5:

Just use this function in your app delegate sandbox for development prod for prodction

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {

    FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.sandbox)

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