如何在 swift 中为推送通知设置 AppDelegate

Question

我正在尝试为我的应用程序设置推送通知系统。我有一个服务器和一个开发人员许可证来设置推送通知服务。

我目前运行我的应用在 Swift4 Xcode 9

这是我的问题：

1_ 可以设置通知消息的标题和body吗？？

2_接受按摩有什么作用？我正在使用 didReceiveRemoteNotification 但是当我触摸通知时会调用它我需要一个函数在显示我可以在其上设置按摩的通知之前调用它

3_ 我在 appDelegate 和我的服务器登录页面中生成设备令牌，它们彼此不同。这不正确吧？

这是我的应用委托：

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

                print("lunch",launchOptions?.description,launchOptions?.first)

                 application.registerForRemoteNotifications()
                FirebaseApp.configure()
                GMSPlacesClient.provideAPIKey("AIzaSyAXGsvzqyN3ArpWuycvQ5GS5weLtptWt14")

                UserDefaults.standard.set(["fa_IR"], forKey: "AppleLanguages")
                UserDefaults.standard.synchronize()


                  registerForPushNotifications()
                return true
            }


       func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {

            print("test : ",messaging.apnsToken)
        }

        func application(application: UIApplication,  didReceiveRemoteNotification userInfo: [NSObject : AnyObject],  fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {

            print("Recived: \(userInfo)")
            print()
           // completionHandler(.newData)

        }


    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {
        print("userInfo : ",userInfo)
        if application.applicationState == .active {
            print("active")
            //write your code here when app is in foreground
        } else {
            print("inactive")

            //write your code here for other state
        }
    }


   func getNotificationSettings() {
        if #available(iOS 10.0, *) {
            UNUserNotificationCenter.current().getNotificationSettings { (settings) in
                print("Notification settings: \(settings)")
                guard settings.authorizationStatus == .authorized else { return }
                DispatchQueue.main.async {
                UIApplication.shared.registerForRemoteNotifications()
                }
            }
        } else {


        }
    }


    func registerForPushNotifications() {
        if #available(iOS 10.0, *) {
            UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) {
                (granted, error) in
                print("Permission granted: \(granted)")
                guard granted else { return }
                self.getNotificationSettings()
            }
        } else {

            let settings = UIUserNotificationSettings(types: [.alert, .sound, .badge], categories: nil)
            UIApplication.shared.registerUserNotificationSettings(settings)
            UIApplication.shared.registerForRemoteNotifications()


           // self.getNotificationSettings()
        }
    }

是的，您可以通过在通知中发送适当的负载来管理通知的内容。以以下模式发送有效负载将在通知

{
        "aps" : {
            "alert" : {
                "title" : "Game Request",
                "body" : "Bob wants to play poker",
            },
            "badge" : 5
        } 
}

显示通知由系统根据应用程序状态处理。如果应用程序处于前台状态，您将在 didReceiveRemoteNotification 中收到调用，否则，系统会处理显示部分并在用户点击通知时在应用程序中获得控制权。

您无法从应用程序端编辑通知内容。

根据文档

APNs can issue a new device token for a variety of reasons:

User installs your app on a new device

User restores device from a backup

User reinstalls the operating system

Other system-defined events

因此建议在启动时请求设备令牌。

您可以在登录页面发送令牌，而不是在登录页面请求新令牌。
