ios - 使用 Swift 的 Firebase 推送通知在 ios 11.4 中不起作用

Question

我正在尝试使用 Swift 在 ios 11.4 上使用 Firebase 设置推送通知，但目前无法正常工作(即，甚至没有出现允许通知的消息)。这是否与我正在为 ios 10 编写代码(这是他们在 Firebase 网站上的内容)有关，或者该代码是否适用于 ios 10 及更高版本。谁能帮我解决这个问题吗？非常感谢!

我有以下AppDelegate代码:

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?
let gcmMessageIDKey = "gcm.message_id"


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

    if #available(iOS 10.0, *) {
        // For iOS 10 display notification (sent via APNS)
        UNUserNotificationCenter.current().delegate = self

        let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
        UNUserNotificationCenter.current().requestAuthorization(
            options: authOptions,
            completionHandler: {_, _ in })
    } else {
        let settings: UIUserNotificationSettings =
            UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
        application.registerUserNotificationSettings(settings)
    }

    application.registerForRemoteNotifications()

    let token = Messaging.messaging().fcmToken
    print("***** MY FCM token: \(token ?? "")")

    return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}

func applicationWillResignActive(_ application: UIApplication) {
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
    // Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
    FBSDKAppEvents.activateApp()
}

func applicationDidEnterBackground(_ application: UIApplication) {
    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}

func applicationWillEnterForeground(_ application: UIApplication) {
    // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
}

func applicationDidBecomeActive(_ application: UIApplication) {
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}

func applicationWillTerminate(_ application: UIApplication) {
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}

func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(application, open: url, sourceApplication: sourceApplication, annotation: annotation)
}


}

// [START ios_10_message_handling]
@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

    // With swizzling disabled you must let Messaging know about the message, for Analytics
    // Messaging.messaging().appDidReceiveMessage(userInfo)

    // Print message ID.
    if let messageID = userInfo[gcmMessageIDKey] {
        print("Message ID: \(messageID)")
    }

    // Print full message.
    print(userInfo)

    // Change this to your preferred presentation option
    completionHandler([.alert, .badge, .sound])
}

func userNotificationCenter(_ center: UNUserNotificationCenter,
                            didReceive response: UNNotificationResponse,
                            withCompletionHandler completionHandler: @escaping () -> Void) {
    let userInfo = response.notification.request.content.userInfo
    // Print message ID.
    if let messageID = userInfo[gcmMessageIDKey] {
        print("Message ID: \(messageID)")
    }

    // Print full message.
    print(userInfo)

    completionHandler()
}
}

// [END ios_10_message_handling]

extension AppDelegate : MessagingDelegate {
// [START refresh_token]
func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {
    print("Firebase registration token: \(fcmToken)")
}
// [END refresh_token]

// [START ios_10_data_message]
// Receive data messages on iOS 10+ directly from FCM (bypassing APNs) when the app is in the foreground.
// To enable direct data messages, you can set Messaging.messaging().shouldEstablishDirectChannel to true.
func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
    print("Received data message: \(remoteMessage.appData)")
}
// [END ios_10_data_message]
}

在我的 ViewController 中包含以下内容:

class ViewController: UIViewController, WKNavigationDelegate, WKScriptMessageHandler {

var webView: WKWebView!
let userContentController = WKUserContentController()

override func loadView() {
    super.loadView()

    let preferences = WKPreferences()
    preferences.javaScriptEnabled=true

    let configuration = WKWebViewConfiguration()
    configuration.preferences=preferences
    configuration.userContentController=userContentController

    webView = WKWebView(frame: self.view.frame, configuration: configuration)
    //webView = WKWebView(frame: self.view.frame)
    let token = Messaging.messaging().fcmToken

    let userScript = WKUserScript(
        source: "change_me(\"\(token ?? "")\")",
        injectionTime: WKUserScriptInjectionTime.atDocumentEnd,
        forMainFrameOnly: true
    )

    userContentController.addUserScript(userScript)
    webView?.configuration.userContentController.add(self, name: "scriptHandler")
    webView.navigationDelegate=self

    self.view.addSubview(webView!)
}

public func userContentController(_ userContentController: WKUserContentController, didReceive message: WKScriptMessage) {
    print("********Message received: \(message.name) with body: \(message.body)")

    let loginManager = LoginManager()
    loginManager.loginBehavior = LoginBehavior.native
    loginManager.logIn( readPermissions: [ReadPermission.publicProfile], viewController: self) { loginResult in
        switch loginResult {
        case .failed(let error):
            print(error)
        case .cancelled:
            print("User cancelled login.")
        case .success(let grantedPermissions, let declinedPermissions, let accessToken):
            print("Logged in!")
            print("\(accessToken)")
        }
    }


}

@IBAction func button(_ sender: UIButton) {

    print("Result: ")
}

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    let taskershopURL = URL(string: "https://www.taskershop.ca")
    let taskershopURLRequest = URLRequest(url:taskershopURL!,cachePolicy: NSURLRequest.CachePolicy.reloadIgnoringLocalCacheData)
    webView?.load(taskershopURLRequest)


    let token = Messaging.messaging().fcmToken
    print("-------- FCM token: \(token ?? "")")

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}


}

首先确保您有付费开发者帐户，激活项目功能部分的通知，使用苹果成员(member)中心设置所有证书并将此证书添加到 gcm(请参阅此 How to use Apple's new .p8 certificate for APNs in firebase console )，您还必须使用真实设备

我假设您已经拥有这 3 个 Pod

import FirebaseInstanceID
import FirebaseMessaging
import UserNotifications

首先您需要将其添加到 didfinishlaunchingwithoptions

FirebaseApp.configure()
Messaging.messaging().delegate = self
registerForPushNotifications()

然后添加这两个函数来获取用户权限

func getNotificationSettings() {
    if #available(iOS 10.0, *) {
        UNUserNotificationCenter.current().getNotificationSettings { (settings) in
            guard settings.authorizationStatus == .authorized else { return }
            DispatchQueue.main.async(execute: {
                UIApplication.shared.registerForRemoteNotifications()
            })
        }
    } else {
        // Fallback on earlier versions
    }
}

func registerForPushNotifications() {
    if #available(iOS 10.0, *) {
        UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) {
            (granted, error) in 
            guard granted else { return }
            self.getNotificationSettings()
        }
    } else {
        let settings = UIUserNotificationSettings(types: [.sound, .alert, .badge], categories: nil)
        UIApplication.shared.registerUserNotificationSettings(settings)
        UIApplication.shared.registerForRemoteNotifications()
    }
}

要获取 firebase token ，请添加此

func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
    print(fcmToken)
}

从现在起，您应该能够看到权限提示并从 Firebase 控制台推送通知

如果您需要通过代码执行通知，这就是我所做的(确保替换为 Firebase 中的 api key )

func sendPushNotification(notData: [String: Any]) {
    let url = URL(string: "https://fcm.googleapis.com/fcm/send")!
    var request = URLRequest(url: url)
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    request.setValue("key=YOUR-SERVER-API-KEY", forHTTPHeaderField: "Authorization")
    request.httpMethod = "POST"

    request.httpBody = try? JSONSerialization.data(withJSONObject: notData, options: [])
    let task = URLSession.shared.dataTask(with: request) { data, response, error in
        guard let data = data, error == nil else {
            print(error ?? "")
            return
        }

        if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 {         
            print("statusCode should be 200, but is \(httpStatus.statusCode)")
            print(response ?? "")
        }

        let responseString = String(data: data, encoding: .utf8)
        print(responseString ?? "")
    }
    task.resume()
}

然后在需要时调用这个函数

let notifMessage: [String: Any] = [
        "to" : "fcm token you need to send the notification",
        "notification" :
            ["title" : "title you want to display", "body": "content you need to display", "badge" : 1, "sound" : "default"]
    ]

sendPushNotification(notData: notifMessage)
