Swift：从 AppDelegate 中的 UNTextInputNotificationAction 获取内容

Question

我正在使用Xcode 9.4.1 (9F2000)和Swift。

我有这个代码AppDelegate：

func showPushButtons(){
    let replyAction = UNTextInputNotificationAction(
        identifier: "reply.action",
        title: "Reply to message",
        textInputButtonTitle: "Send",
        textInputPlaceholder: "Input text here")

    let pushNotificationButtons = UNNotificationCategory(
        identifier: "allreply.action",
        actions: [replyAction],
        intentIdentifiers: [],
        options: [])

    UNUserNotificationCenter.current().setNotificationCategories([pushNotificationButtons])
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

    let action = response.actionIdentifier
    let request = response.notification.request
    let content = response.notification.request.content.userInfo

    print("\(action)\(request)\(content)")

    if let aps = content["aps"] as? [String: AnyObject] {
        dump(aps)
    }

    completionHandler()
}

它能做什么：

收到推送通知时，将显示一个文本字段并显示键盘。我可以写消息并提交。

我的问题是：我怎样才能得到这个提交的消息AppDelegate来处理它（发送到我的服务器左右）？

随着print("\(action)\(request)\(content)")我检查的消息不是action，request或content。

如您所见，我还检查了它是否在 aps 负载中，但不是。

此代码现在有效：

func showPushButtons(){
    let replyAction = UNTextInputNotificationAction(
        identifier: "reply.action",
        title: "Reply on message",
        textInputButtonTitle: "Send",
        textInputPlaceholder: "Input text here")

    let pushNotificationButtons = UNNotificationCategory(
        identifier: "allreply.action",
        actions: [replyAction],
        intentIdentifiers: [],
        options: [])

    UNUserNotificationCenter.current().setNotificationCategories([pushNotificationButtons])
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

    if  response.actionIdentifier  ==  "reply.action" {
        if let textResponse =  response as? UNTextInputNotificationResponse {
            let sendText =  textResponse.userText
            print("Received text message: \(sendText)")
        }
    }
    completionHandler()
}

它的作用：如果您收到推送通知"category":"allreply.action"并用力点击它，将出现一个文本字段和键盘，您可以使用print("Received text message: \(sendText)").

不要忘记showPushButtons()从didFinishLaunchingWithOptions应用程序中调用并准备接收（远程）推送通知。
