Ich verwende Firebase mit meiner IOS-App und versuche, Push-Benachrichtigungen einzurichten.Wie bekomme ich FCM-Benachrichtigungen, während die App im Hintergrund läuft (ios)?
Momentan kann ich Push-Benachrichtigungen empfangen, während meine App im Vordergrund ist, aber wenn ich sie in den Hintergrund stelle, kann ich keine empfangen.
In meinen App-Funktionen habe ich Push-Benachrichtigungen sowie Remote-Benachrichtigungen im Abschnitt Hintergrundmodi aktiviert.
ich derzeit Postman bin mit der folgenden POST-Anfrage senden:
https://fcm.googleapis.com/fcm/send
Content-Type:application/json
Authorization:key=<my_server_key>
{ "to" : "token_id",
"priority":"high",
"data":{
"title":"mytitle",
"body":"mybody",
"url":"myurl"
},
"notification":{
"title":"mytitle",
"body":"mybody",
"content_available": true
}
}
Nachdem ich die Anfrage sende ich den Status 200 und folgende Antwort erhalten:
{
"multicast_id": 7920502412622407470,
"success": 1,
"failure": 0,
"canonical_ids": 0,
"results": [
{
"message_id": "0:1469561276461379%345a0fe5f9fd7ecd"
}
]
}
ich diese beide gefolgt Anleitungen zum Einrichten des Sendens beim Empfangen von Nachrichten:

Hier ist meine AppDelegate Datei:

application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
// [END register_for_notifications]
} else {
// Fallback
let types: UIRemoteNotificationType = [.Alert, .Badge, .Sound]
application.registerForRemoteNotificationTypes(types)
}
// Add observer for InstanceID token refresh callback.
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.tokenRefreshNotification), name: kFIRInstanceIDTokenRefreshNotification, object: nil)

func applicationWillResignActive(application: UIApplication) {

// Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
}
func applicationDidEnterBackground(application: UIApplication) {
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
FIRMessaging.messaging().disconnect()
print("Disconnected from FCM.")
}
func applicationWillEnterForeground(application: UIApplication) {
// Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
}
