Ios Swift：从AppDelegate中的UNTextInputNotificationAction获取内容

我使用的是Xcode 9.4.1 9F2000和Swift

我在AppDelegate中有以下代码：

它的作用是：

收到推送通知时，将显示文本字段并显示键盘。我能够写一条信息并提交

我的问题是：如何在AppDelegate中获取此已提交的消息，以便将其发送到服务器上

使用print\action\request\content，我检查了消息是否处于活动、请求或内容中

如您所见，我还检查了它是否在aps有效负载中，但它不在aps有效负载中。

此代码现在起作用：

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()
}

功能：如果您收到类别为：allreply.action的推送通知，并在其上进行强制触摸单击，则会出现文本字段和键盘，您可以使用printReceived文本消息：\sendText打印它

不要忘记从didFinishLaunchingWithOptions调用Show按钮，并准备应用程序以接收远程推送通知

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()
}
