如何通過FCM（Firebase）或本機在iOS 10中發送推送通知？

Question

我正在開發一個部署目標為iOS 7.1的應用程序。 我正在使用Firebase進行推送通知。 推送通知在iOS 9設備中正常運行。 但不適用於iOS 10設備。

當我搜索時，我在這里找到了這個注釋。

if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_9_x_Max) {
  UIUserNotificationType allNotificationTypes =
  (UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
  UIUserNotificationSettings *settings =
  [UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
  [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
} else {
  // iOS 10 or later
  #if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0
  UNAuthorizationOptions authOptions =
      UNAuthorizationOptionAlert
      | UNAuthorizationOptionSound
      | UNAuthorizationOptionBadge;
  [[UNUserNotificationCenter currentNotificationCenter]
      requestAuthorizationWithOptions:authOptions
      completionHandler:^(BOOL granted, NSError * _Nullable error) {
      }
   ];

  // For iOS 10 display notification (sent via APNS)
  [[UNUserNotificationCenter currentNotificationCenter] setDelegate:self];
  // For iOS 10 data message (sent via FCM)
  [[FIRMessaging messaging] setRemoteMessageDelegate:self];
  #endif
}

而且這個說明：

重要提示：對於運行iOS 10及更高版本的設備，必須將委托對象分配給UNUserNotificationCenter對象以接收顯示通知。

是否有必要通過此方法發送推送通知（這是一個新類UNUserNotificationCenter ）？ 是否有可能通過舊的推送通知注冊方法？

請告訴我。 因此，我需要將我的項目更新為Swift版本2.3或3.0，這需要時間。

Firebase文檔中的示例已過時。 這是最新的Xcode 8和Swift 3的代碼：

import Firebase
import FirebaseMessaging
import UserNotifications

class AppDelegate: UIResponder, UIApplicationDelegate {


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


        FIRApp.configure()

        if #available(iOS 10.0, *) {
            let authOptions : UNAuthorizationOptions = [.alert, .badge, .sound]
            UNUserNotificationCenter.current().requestAuthorization(
                options: authOptions,
                completionHandler: {_,_ in })

            // For iOS 10 display notification (sent via APNS)
            UNUserNotificationCenter.current().delegate = self
            // For iOS 10 data message (sent via FCM)
            FIRMessaging.messaging().remoteMessageDelegate = self

        }

        application.registerForRemoteNotifications()

        return true
    }
}


@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {

    // Receive displayed notifications for iOS 10 devices.

    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        let userInfo = notification.request.content.userInfo
        // Print message ID.
        print("Message ID: \(userInfo["gcm.message_id"]!)")

        // Print full message.
        print("%@", userInfo)

    }

}

extension AppDelegate : FIRMessagingDelegate {
    // Receive data message on iOS 10 devices.
    func applicationReceivedRemoteMessage(_ remoteMessage: FIRMessagingRemoteMessage) {
        print("%@", remoteMessage.appData)
    }
}
