IOS - 通过单击 UNNotificationAction 处理后丰富的推送重复

Question

在后台处理丰富的推送后(用户在没有打开应用程序的情况下单击了 UNNotificationAction - 没有前台))，然后当您进入应用程序时，会出现重复的推送事件，导致“didReceiveRemoteNotification”执行。

我的问题是:

为什么当我处理丰富的推送时:

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

并调用 competionHandler()，在以下位置接收到相同的推送:

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void)

?

推送设置:

UNUserNotificationCenter.current().delegate = self

UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { (granted, error) in
                if granted {
                    print("UNUserNotificationCenter auth granted")
                    Utils.performTaskOnMain {
                        application.registerForRemoteNotifications()
                    }
                } else {
                    print("UNUserNotificationCenter auth error = \(error?.localizedDescription ?? "")")

                }

推送处理程序

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void)
    {
        print("AppDelegate didReceiveRemoteNotification, with info:\(userInfo)")
        handleNotificationUserInfo(userInfo)
        completionHandler(UIBackgroundFetchResult.newData)
    }


    @available(iOS 10.0, *)
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
                 UserNotificationsManager.shared.handleActionIdentifierForReceivedNotification(response)
         completionHandler()
    }

推送通知负载:

info:[AnyHashable("content-available"): 1, AnyHashable("messageInfo"): {"push_type":"XXXX","category":"videoCategory","mediaUrl":"https://XXXX.png","threadId":"24274","alertTitle":null,"initiator":"XXXXX XXXX.mp3","alertBody":null,"mutableContent":true}, AnyHashable("media-url"): https://XXXXX.png, AnyHashable("aps"): {
alert =     {
    body = "XXXXX";
};
badge = 56;
category = "XXX.videoCategory";
"content-available" = 1;
"mutable-content" = 1;
sound = "XXXX.mp3";

}]

Answer 1

传递到您的应用程序的“重复”推送是静默推送通知。除了 alert 字典之外，您的推送通知还包含 content-available 键。

alert 字典会导致传递用户可见的通知。

content-available 键导致它作为静默推送通知再次传送，这对用户是不可见的。

这是一个不受支持的配置。删除 content-available 键，将只发送用户可见的推送通知。如果您正在积极使用静默推送，请将其作为单独的推送发送，仅包含 content-available、category 和您的自定义 key 。
