如何保存 pushNotification 附带的两个项目

Question

1)收到通知时，我需要保存来自 AnyHashable("data") "amount" 和 "inBalance"?

的数据

2) 从服务器发出两次推送，第一次推送 "message"，第二次推送 "nil message body"。当出现 nil 消息时，我需要静音吗？我怎样才能保存它？我正在使用 xCode 10.2.1

我的 pushNotification.swift 代码如下：

enum PillikanRemoteNotification:Int {
    case empty
    case notification = 2
    case news = 3
}

class PushManagerNotification {
    func convert(with value: [AnyHashable: Any], and state: PushNotificationAction) {
        guard let json = value as? [String: AnyObject], !json.isEmpty else { return }
        guard let jsonString = value["data"] as? String, !jsonString.isEmpty else { return }
        guard let jsonData = jsonString.data(using: .utf8) else { return }
        guard let rawDictionary = try? JSONSerialization.jsonObject(with: jsonData, options: .mutableLeaves) else { return }
        guard let dictionary = rawDictionary as? [String: AnyObject] else { return }
        guard let actionType = dictionary["action"] as? String, let action = Int(actionType) else { return }
        guard let notificationType = PillikanRemoteNotification(rawValue: action) else { return }
        guard let messageBody = dictionary["msg"] as? [String: AnyObject] else { return }

        if state == .show {
            showBadges(dictionary: messageBody)
            return
        }

        switch notificationType {
        case .notification:
            showNotification(dictionary: messageBody)
            break
        default:
            break;
        }
    }

    private func showBadges(dictionary: [String: AnyObject]) {
        guard let badgeMessage = dictionary["badges"] as? [String: AnyObject] else { return }
        guard let badges = Badges(JSON: badgeMessage) else { return }
        UIApplication.shared.notificationBadgesForNotification = badges.notifications
        UIApplication.shared.notificationBadgesForNews = badges.news
        UIApplication.shared.applicationIconBadgeNumber = badges.news + badges.notifications
        NotificationCenter.default.post(name: .badges, object: badges)
    }

    private func showNotification(dictionary: [String:AnyObject]) {
        if let message = NotificationEntity(JSON: dictionary) {
            NotificationCenter.default.post(name: .notification, object: message);
        }
    }

extension Notification.Name {
    static let empty = Notification.Name("empty");
    static let notification = Notification.Name("notification");
    static let news = Notification.Name("news");
    static let badges = Notification.Name("badges")
}

Answer 1

在 didReceive 函数中使用这个：

let amount =  userInfo["data"]["amount"]
let inBalance = userInfo["data"]["inBalance"]

我不确定这是否有效我没有尝试过.. 试试这个通知属性的功能：

@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {


    let userInfo = notification.request.content.userInfo
    let message = userInfo["message"] as! String
    if message.isEmpty == true {

        completionHandler([.alert, .badge])
    }else {

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



}

Answer 2

对于静默通知有两个标准：

1.) 负载的 aps 字典必须包含值为 1 的 content-available 键。

2.) 负载的 aps 字典不得包含警报、声音或徽章键。

例子

{ "aps"：{ "content-available"：1 }, "cusomtkey1" : "bar", "cusomtkey2" : 42 }

Answer 3

在这里你可以看到，我是如何从 AnyHashable 中获取令牌，然后从中获取特定值的。

试试这个代码。它会帮助你。

if(response.result.isSuccess){
       let data = response.result.value
          print(data!)
            if (data?.contains("access_token"))!{
                var dictonary:NSDictionary?
                    if let data = data!.data(using: String.Encoding.utf8) {
                       do {
                            dictonary = try JSONSerialization.jsonObject(with: data, options: []) as? [String:AnyObject] as NSDictionary?

                                UserDefaults.standard.set(dictonary!["access_token"]!, forKey: "token")


                            }catch let error as NSError {
                                print(error)
                            }
                        }
                     }
                   }
