Firebase云消息传递AppDelegate错误

Question

这是Firebase文档中的代码。

if #available(iOS 10.0, *) {
        let authOptions : UNAuthorizationOptions = [.Alert, .Badge, .Sound]
        UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions(
            authOptions,
            completionHandler: {_,_ in })

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

    } else {
        let settings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
        application.registerUserNotificationSettings(settings)
    }

我没有修改任何代码行。 但是Xcode说“使用未声明的类型UNAuthorizationOptions ， UNUserNotificationCenter ， FIRMessagingDelegate ”

我还有一条线。

NotificationCenter.defaultCenter.addObserver(self,selector: #selector(self.tokenRefreshNotification),name: kFIRInstanceIDTokenRefreshNotification,object: nil)

它说“AppDelegate类型的值没有成员tokenRefreshNotification ”

我刚从firebase文档中复制并粘贴了我的代码，但是有错误！

Firebase文档中的示例已过时。 这是最新的Xcode 9和Swift 3的代码：

import Firebase
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)
             Messaging.messaging().delegate = 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 : MessagingDelegate {
// Receive data message on iOS 10 devices.
func applicationReceivedRemoteMessage(_ remoteMessage: MessagingRemoteMessage) {
    print("%@", remoteMessage.appData)
    }
}

Answer 2

别忘了

导入FirebaseMessaging

导入UserNotifications

Answer 3

您需要将以下导入添加到您的文件中：

import Firebase
import FirebaseMessaging
import UserNotifications

您还需要一个名为tokenRefreshNotification的方法，类似于以下内容：

func tokenRefreshNotification() {
    let fcmDeviceToken = FIRInstanceID.instanceID().token()
    // TODO: Send token to server
}

Answer 4

对于swift 2.0，添加FIRMessagingDelegate协议

class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, FIRMessagingDelegate{}
func applicationReceivedRemoteMessage(remoteMessage: FIRMessagingRemoteMessage){}

Answer 5

Swift 2.3版本的Alexey的回答是：

if #available(iOS 10.0, *) {
            let authOptions: UNAuthorizationOptions = [.Alert, .Badge, .Sound]
            UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions(authOptions, completionHandler: {_, _ in})

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

        } else {
            let settings: UIUserNotificationSettings =
                UIUserNotificationSettings(forTypes: [.Alert , .Badge, .Sound], categories: nil)
            application.registerUserNotificationSettings(settings)
        }

        application.registerForRemoteNotifications()

和..

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

    // Receive displayed notifications for iOS 10 devices.

    func userNotificationCenter(center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: (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)
    }
}
