【问题描述】：

我有社交网络应用，并且...我想知道这个应用是否可以在锁定屏幕上对通知进行分组。

我的远程服务器向 APNs 发送通知，然后我通过设备令牌接收它。有没有办法按应用程序分组通知？我在 medium 上找到了代码，但我不知道如何实现它。

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) 

    //over here add condition if same user has opened chat and notification is also from same user dont show these
    let extraPayLoad = (notification.request.content.userInfo["extraPayLoad"] as? [AnyHashable : Any])
    if extraPayLoad!["custom"] != nil 
        let info_string = extraPayLoad!["custom"] as? String

        let objectData: Data? = info_string?.data(using: String.Encoding(rawValue: String.Encoding.utf8.rawValue))
        var json: [AnyHashable : Any]? = nil
        if let aData = objectData 
            json = try! JSONSerialization.jsonObject(with: aData, options: .mutableContainers) as? [AnyHashable : Any]
        
        if json?["sender_id"] != nil 
            if let aKey = json?["sender_id"] 
                print("sender_id : \(aKey)")
            

            if(json?["code"] as? Int ?? 0 != 1003 && json?["code"] as? Int ?? 0 != 1004)
            
                let unread_count_dict:[String: Bool] = ["unread_count":  true]
                NotificationCenter.default.post(name: NSNotification.Name(rawValue: "showNotificationView"), object: nil, userInfo: unread_count_dict)
            
            if (UserDefaults.standard.value(forKey: "_targetId") as? String ?? "0") == "\((json?["sender_id"] as? Int ?? -1))" 
                //
                // NotificationCenter.default.post(name: NSNotification.Name("GetAllConversationsList"), object: self)
                //return
            
            if (UserDefaults.standard.value(forKey: "_groupId") as? String ?? "0") == "\((json?["group_id"] as? Int ?? -1))" 
                // NotificationCenter.default.post(name: NSNotification.Name("GetAllConversationsList"), object: self)
                //return
            

        
    
    completionHandler([.sound, .alert, .badge])

如果有人需要回答……

只需将带有任何标识符的 thread-id 字段添加到您的服务器，push not 将自动按此 ID 分组...）
