J'essaie d'utiliser FCM pour la notification.
Mais <FIRInstanceID/WARNING>
Échec lors de l'extraction du jeton APNS
Une erreur Domain=com.firebase.iid Code=1001 "(null)"
s'est produite et je ne peux donc pas recevoir de notification. Quel est le problème?
À la console,
Impossible d'extraire le jeton APNS
et Error Domain=com.firebase.iid Code=1001 "(null)"
et ci-dessous est mon code sur Appdelegate

Pour moi, j'ai essayé de suivre les petits coups pour que cela fonctionne:
Vous pouvez toujours recevoir l'avertissement, mais si vous essayez d'envoyer une notification à partir de la console firebase en utilisant le jeton d'actualisation, cela fonctionnera.
Il semble que le serveur que vous utilisez pour envoyer la notification à distance puisse avoir un ancien enregistrement de votre jeton FCM. Les documents Google FCM indiquent que le jeton FCM peut être pivoté (modifié) lorsque:
Ils citent la bonne pratique pour mettre à jour l'enregistrement de ce jeton sur votre serveur en utilisant une méthode de rappel par délégué:
func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {
// Send the token to your server here
}
Cette méthode ne fonctionnait pas pour moi, je devais donc la mettre à jour manuellement à chaque lancement d'application (après un délai d'environ 20-25 secondes, la rotation n'étant pas toujours instantanée). Vous pouvez le faire avec:
let token = Messaging.messaging().fcmToken // Send this to your server
Après ces modifications, je reçois toujours le message du journal de la console d’avertissement, mais les notifications Push fonctionnent parfaitement à chaque fois.
