I am tring to implement push notification in iOS. I have successfully made it working once. But now I am facing a strange issue. I have exited XCode and reopened it, no code was changed, I am still getting the deviceToken, but now I am not receiving any push notification on my device. I am also using Firebase to get the notification, it was also working fine, but now it is giving me blank string as device token.
In AppDelegate I am using the following code:
if #available(iOS 10.0, *) {
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.current().delegate = self
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(
options: authOptions,
completionHandler: {_, _ in })
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
//This is triggered and I am getting the push notification token but using this instead of firebase token to send directly via APNS is also not working.
public func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Messaging.messaging().setAPNSToken(deviceToken, type: .sandbox)
}
//This is triggered but the token here is a blank string
func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {
Messaging.messaging().subscribe(toTopic: "ios_topic")
}
This was working till I quit XCode, but suddenly it stopped working without any code changes. I tried everything including a system restart. Sometimes the didRegisterForRemoteNotificationsWithDeviceToken is getting called twice during fresh installs, once before I give permissions and once after the permissions are granted.
