Swift:从AppDelegate中的UNTextInputNotificationAction获取内容

Question

我使用的是Xcode 9.4.1 (9F2000)和Swift。

我在AppDelegate:中有这个代码

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()
}

它的作用：

当收到推送通知时，将显示一个文本字段并显示键盘。我可以写一条消息并提交。

我的问题是：如何在我的AppDelegate中获得此提交的消息来处理它(发送到我的服务器左右(？

对于print("(action)(request)(content)")，我检查了消息不在action、request或content中。

正如你所看到的，我也检查了它是否在aps有效载荷中，但它不是。

此代码现在可以工作：

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：如果你收到一个带有"category":"allreply.action"的推送通知，并且你在它上进行了强制触摸点击，就会出现一个文本字段和键盘，你可以用print("Received text message: (sendText)")打印它。

别忘了从didFinishLaunchingWithOptions呼叫showPushButtons()，并为应用程序接收(远程(推送通知做好准备。
