iOS内使用谷歌推送相关的代码

1.添加头文件

    import Firebase
    import FirebaseMessaging

2.遵守协议

class AppDelegate: UIResponder, UIApplicationDelegate,UNUserNotificationCenterDelegate,MessagingDelegate{

3.appDelegate内的代码

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

   // 谷歌推送相关
    self.setUpFirebaseConfigure(application)
}

4.协议方法

    func setUpFirebaseConfigure(_ application:UIApplication){
    FirebaseApp.configure()
    Messaging.messaging().delegate = self
    
      // For iOS 10 display notification (sent via APNS)
    UNUserNotificationCenter.current().delegate = self

    let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
    UNUserNotificationCenter.current().requestAuthorization(options: authOptions) { ret, error in
            print("ret == \(ret)")
            print("error == \(error)")
    }
    application.registerForRemoteNotifications()
    
}

//获取token
internal func application(_ application: UIApplication,
                 didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    
    print("deviceToken==\(deviceToken)")
    Messaging.messaging().apnsToken = deviceToken
    
}

//注册token
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String?) {
  print("Firebase registration token: \(String(describing: fcmToken))")

  let dataDict: [String: String] = ["token": fcmToken ?? ""]
  NotificationCenter.default.post(
    name: Notification.Name("FCMToken"),
    object: nil,
    userInfo: dataDict
  )
}

}

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

    let userInfo = notification.request.content.userInfo

}

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    
    let userInfor = response.notification.request.content.userInfo
