我已经按照他们网站上的说明实施了 Firebase 云消息传递。所以当我从这里生成通知时：
在AppDelegate.swift我添加了didReceiveRemoteNotification以下功能：
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
Messaging.messaging().appDidReceiveMessage(userInfo)
print(userInfo)
completionHandler(UIBackgroundFetchResult.newData)
}
我实施的其他方法是
func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String)
func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage)
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
而我的didFinishLaunchingWithOptions有：
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 })
// For iOS 10 data message (sent via FCM
Messaging.messaging().delegate = self
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
FirebaseApp.configure()
NotificationCenter.default.addObserver(self, selector: #selector(self.tokenRefreshNotification), name: NSNotification.Name.InstanceIDTokenRefresh, object: nil)
return true
