Я уже давно пытаюсь получить push-уведомление firebase в своем приложении для ios. Я перепробовал все, что смог найти в Интернете. Но, к сожалению, не повезло.
Любая помощь будет оценена.

Я отправляю уведомление через консоль firebase. И иногда, когда приложение работает на переднем плане, последняя часть

 extension AppDelegate : FIRMessagingDelegate {
    // Receive data message on iOS 10 devices.
    func applicationReceivedRemoteMessage(_ remoteMessage: FIRMessagingRemoteMessage) {
        print("noti recieve remote notification in extesnion")
         print("%@ debug", remoteMessage)
        print("%@", remoteMessage.appData)

    }
 

вызывается, но ничего не происходит, когда приложение работает в фоновом режиме. Я включил «Push-уведомления» и фоновые режимы» в возможностях.

Я тестировал это только на устройстве ios 10.

Вот мой код в AppDelegate.swift

}
 

Я решил проблему, добавив приведенный ниже код в проект.

FIRInstanceIDAPNSTokenType.Sandbox будет использоваться при установке приложения через TestFlight
и FIRInstanceIDAPNSTokenType.Нажмите, когда ваше приложение появится в App Store.

 func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) 
{
    FIRInstanceID.instanceID().setAPNSToken(deviceToken, type:FIRInstanceIDAPNSTokenType.Sandbox)
    FIRInstanceID.instanceID().setAPNSToken(deviceToken, type:FIRInstanceIDAPNSTokenType.Prod)
}
 

Попробуйте это. Это работает.

Удивительно, но все, что я сделал, чтобы устранить проблему, на самом деле заключалось в удалении и переустановке приложения. Надеюсь, это поможет.

Спасибо, что задали этот вопрос.

Обязательно использовать приведенную ниже инструкцию, пока вы комментируете эту строку в коде

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

Раскомментируйте приведенный ниже код…

Надеюсь, это вам поможет…
