【问题描述】：

我已将自定义远程通知内容扩展添加到我的项目中，并将多个扩展类别添加到 通知内容扩展目标 info.plist 文件中，如下所示：

在AppDelegate中为不同的通知添加了不同类型的通知操作类别：

 func addRichRotificationActions() {
        let confirmAction = UNNotificationAction(identifier: "ConfirmAction", title: "Confirm", options: [.foreground])
        let cancelAction = UNNotificationAction(identifier: "CancelAction", title: "Cancel", options: [.destructive])
        let closeAction = UNNotificationAction(identifier: "CloseAction", title: "Close", options: [.foreground])

        let openTicketCategory = UNNotificationCategory(identifier: "OpenTicket", actions: [confirmAction, cancelAction], intentIdentifiers: [], options: [])
        let confirmTicketCategory = UNNotificationCategory(identifier: "ConfirmTicket", actions: [closeAction, cancelAction], intentIdentifiers: [], options: [])
        let closeTicketCategory = UNNotificationCategory(identifier: "CloseTicket", actions: [], intentIdentifiers: [], options: [])
        let cancelTicketCategory = UNNotificationCategory(identifier: "CancelTicket", actions: [], intentIdentifiers: [], options: [])

        UNUserNotificationCenter.current().setNotificationCategories([openTicketCategory, confirmTicketCategory, closeTicketCategory, cancelTicketCategory])
    }

现在我通过以下方式发送 apns json：

对于 OpenTicket 获取类别名称为 "OpenTicket"：

[AnyHashable("default"): You have a new ticket, AnyHashable("aps"): {
    alert = "#8556 - New Booking for Mr. Tomas";
    badge = 1;
    category = OpenTicket;
    "mutable-content" = 1;
    sound = default;
}]

对于ConfirmTicket，将类别名称设为“ConfirmTicket”：

[AnyHashable("default"): You have a confirmed ticket, AnyHashable("aps"): {
    alert = "#8556 - Ticket Confirmed for Mr. Tomas";
    badge = 1;
    category = ConfirmTicket;
    "mutable-content" = 1;
    sound = default;
}]

等等。

但不幸的是，我收到的是带有不同操作按钮的默认通知，而不是带有不同操作的自定义通知内容扩展。我无法弄清楚问题所在。如何获得具有不同远程通知操作的通知内容扩展？

【解决方案1】：

只需要在Notification Content Extension目标的info.plist中将UNNotificationExtensionCategory设为Array而不是String。
