Swift Push、標準とFirebase Message、registerForRemoteNotifications()

UIApplication.shared.registerForRemoteNotifications()コール、標準とFirebase Messageでトークンを待ち受けてみる。

標準

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {

Firebase Message

func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {

結果

両方コールされる。
標準「didRegisterForRemoteNotificationsWithDeviceToken」でInstanceID〜を使用する事FMCトークンも取得出来る。
正しいやり方は分かりませんが。両方欲しい場面がある可能性もほぼありませんが。
→InstanceID〜は非同期になってしまう為、両方欲しいという意味ではちょっと違いますね。非同期であれば取れますというだけ。

コード

import UIKit
import UserNotifications
import Firebase

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, MessagingDelegate {



    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.

        FirebaseApp.configure()
        Messaging.messaging().delegate = self
        
        UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { granted, error in
            guard granted else {
                return
            }
            print("許可")
            DispatchQueue.main.async {
                UIApplication.shared.registerForRemoteNotifications()
            }
        }
        return true
    }

    // MARK: UISceneSession Lifecycle

    func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
        // Called when a new scene session is being created.
        // Use this method to select a configuration to create the new scene with.
        return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
    }

    func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
        // Called when the user discards a scene session.
        // If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
        // Use this method to release any resources that were specific to the discarded scenes, as they will not return.
    }


}

extension AppDelegate {
    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        let tokenBytes = deviceToken.map { (byte: UInt8) in String(format: "%02.2hhx", byte) }
        print("Device token: \(tokenBytes.joined())")
        
        InstanceID.instanceID().instanceID { (result, error) in
          if let error = error {
            print("Error fetching remote instance ID: \(error)")
          } else if let result = result {
            print("Remote instance ID token: \(result.token)")
          }
        }
    }
    
    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
        print("didFailToRegisterForRemoteNotificationsWithError")
    }
    
    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
        print("fcmToken: \(fcmToken)")
    }
    
}
