IONIC 3: onNotification not fire in foreground in IOS?

问题

I have implemented push notification in ionic Everything working fine on android and but in IOS got different scenario:

in foreground : onNotification is not fired as well as android working perfect.
Background: push notification is received but after tap from notification nothing happend

app.component.ts

this.fcm.onNotification().subscribe(data => {
if(data.wasTapped){
  console.log(data.wasTapped);
     //redirectPageViaNotificationType for redirect page...
     this.redirectPageViaNotificationType(data);
}  else {
    //Notification was received in foreground. Maybe the user needs to be notified
      // if application open, show
    let confirmAlert = this.alertCtrl.create({
      title: (<any>data).title,
      message: (<any>data).body,
      buttons: [{
        text: 'Ignore',
        role: 'cancel'
      },{
        text: 'View',
        handler: () => {
            //redirectPageViaNotificationType for redirect page...
          this.redirectPageViaNotificationType(data);
        }
      }]
    });
    confirmAlert.present();
}
});

when any push notification is received its showing notification when my application is closed or background it does not executing the this.fcm.onNotification()function. And i just debug this issue and noticed this, in my xcode console its showing:

回答1:

I spent a lot of time on this problem, but I could not get the fcm plugin to work stably in ios. This problem was reproduced when the application was killed. I think the fcm plugin does not work too well with ios. I was trying to use phonegap-plugin-push and everything is working fine. This plugin can work with fcm and apns, and notification caught even when the ios application was killed.

If you want to handle the requests, ie not just process some data in the background as you would with content-available: '1', you must leave it as content-available: '0'.

I process Push notifications with PHP and Kreait/Firebase. Then for iOS this is my config:

  $notification = Notification::fromArray([
    'title' => $title,
    'body'  => $message,
  ]);

  $data = MessageData::fromArray([
    'some_key' => $value,
  ]);

  $apnsConfig = ApnsConfig::fromArray([
    'payload' => [
      'aps' => [
        'badge' => 1,
        'content-available' => 0,
        'notId' => UUID::v4()
      ],
    ],
  ]);

  $cloudMessage = CloudMessage::new()
    ->withNotification($notification)
    ->withData($data)
    ->withApnsConfig($apnsConfig);

  $apnsResult = self::$messaging->sendMulticast($cloudMessage, $iosTokens);

You can find the documentation here: https://firebase.google.com/docs/cloud-messaging. For Android I used curl however, there was some problem back then with kreaits' fcm implementation. They did publish a new release that I ment to check whether it fixed this.

Hope this helps.
