Plate-forme: iOS 10.2+FCM Xamarin.Forms, notification de fond iOS ne montre pas
Xamarin Plugin: Firebase iOS messagerie nuage https://components.xamarin.com/view/firebaseioscloudmessaging
Problème: Lorsque j'envoie une notification de la console Firebase ou à partir de mon code appelant FireBase. Mes iPhones ne reçoivent pas les notifications d'arrière-plan (comme une bulle). Mais, si j'avais l'application en premier plan, j'ai reçu la notification en tant que "DisplayAlert" de la fonction ApplicationReceivedRemoteMessage (RemoteMessage remoteMessage). Par conséquent, l'appareil est enregistré sur FCM, l'appareil possède le jeton, l'appareil peut recevoir les notifications, mais l'appareil n'a pas reçu les notifications en arrière-plan.
** En VisualStudio 2017 au projet .iOS manifeste Je le mode de fond activé et les notifications activées à distance trop **
¿C'est-ce un problème commun? Puis-je résoudre pour travailler à mon projet?
