iOS10、Swift 3 和 FCM 委托(delegate)错误

Question

我遇到错误:

"Value of type FIRMessaging has no member 'remoteMessageDelegate'" on FIRMessaging.messaging().remoteMessageDelegate = self

我从 FCM 设置指南中获得了这段代码:

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

    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 //Get error on this line

    } else {
        let settings: UIUserNotificationSettings =
            UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()
    }

我遇到了同样的问题。看来谷歌文档已经过时了，我看了一下Cocoapods Firebase Messaging page我解决了在终端内更新 cocoapods 仓库的问题:

pod repo update

然后替换我的 Podfile 中的以下行:

pod 'Firebase/Core'
pod 'Firebase/Messaging'

与:

 pod 'Firebase', '~> 3.7'
 pod 'FirebaseMessaging', '~> 1.2'
 pod 'FirebaseAnalytics', '~> 3.3'

这将下载 FirebaseMessaging 1.2 而不是 1.1
