使用Swift的Firebase推送通知在ios 11.4中不起作用

我正在尝试使用Swift在ios 11.4上使用Firebase设置推送通知，但它目前无法正常工作（即使消息无法通知）。 是否与我为ios 10编写代码这一事实有关（这是他们在Firebase网站上的代码），或者此代码是否适用于ios 10及更高版本。 任何人都可以帮我这个。 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] } 

以及我的ViewController的以下内容：

 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. } }

首先确保您拥有付费开发者帐户，从项目function部分激活通知，使用Apple成员中心设置所有证书并将此证书添加到gcm（请参阅此如何在firebase控制台中使用Apple的新.p8证书进行APN ） ，您还必须使用真实设备进行测试

我假设你已经拥有这3个Pod

 import FirebaseInstanceID import FirebaseMessaging import UserNotifications 

首先，您需要将此添加到didfinishlaunchingwithoptions

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

然后添加这两个func以获得用户权限

 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() } } 

获取firebase令牌添加此项

 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

如果你需要从代码执行通知这就是我做的（确保用firebase中的api密钥替换）

 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() } 

然后在需要时调用此函数

 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)
