ios - 如何通过 FCM(Firebase) 或 native 在 iOS 10 中发送推送通知？

Question

我正在开发一个部署目标为 iOS 7.1 的应用程序。我将 Firebase 用于推送通知。推送通知在 iOS 9 设备上运行良好。但不适用于 iOS 10 设备。

当我搜索时，我发现了这个笔记 here .

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
}

还有这个注释:

Important: for devices running iOS 10 and above, you must assign your delegate object to the UNUserNotificationCenter object to receive display notifications.

是否需要通过此方法(这是一个新类 UNUserNotificationCenter)发送推送通知？是否可以通过旧的推送通知注册方式？

请告诉我。因此，我需要将我的项目更新到 Swift 2.3 或 3.0 版本，这需要时间。

Firebase 文档中的示例已过时。这是最新的 Xcode 8 和 Swift 3 的代码:

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)
    }
}
