Question

这是我注册通知操作的方式

func registerForPushNotifications() {
    UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) {
        (granted, error) in
        print("Permission granted: \(granted)")

        guard granted else { return }

        let action = UNTextInputNotificationAction(identifier: replyActionIdentifier, title: "Answer message", options: [UNNotificationActionOptions.init(rawValue: 0)], textInputButtonTitle: "Send", textInputPlaceholder: "Type your message")

        let newsCategory = UNNotificationCategory(identifier: categoryIdentifier,
                                                  actions: [action],
                                                  intentIdentifiers: [],
                                                  options: [])

        UNUserNotificationCenter.current().setNotificationCategories([newsCategory])

        self.getNotificationSettings()
    }
}

这里我遵守协议UNUserNotificationCenterDelegate并处理通知操作

extension AppDelegate: UNUserNotificationCenterDelegate {

func userNotificationCenter(_ center: UNUserNotificationCenter,
                            didReceive response: UNNotificationResponse,
                            withCompletionHandler completionHandler: @escaping () -> Void) {

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

    // check if there is information in push's payload
    guard let custom = userInfo["data"] as? [String: AnyObject] else {
        completionHandler()
        return
    }

    switch response.actionIdentifier {
    case replyActionIdentifier:

        if let message = response as? UNTextInputNotificationResponse {
            if message.userText.isEmpty { return }

            // encrypt the message
            let publicKey = try! PublicKey(pemEncoded: Constantes.PUSH_KEY)
            let clear = try! ClearMessage(string: message.userText, using: .utf8)
            let encrypted = try! clear.encrypted(with: publicKey, padding: .PKCS1)
            let messageUser = encrypted.base64String

            // data inside the push
            guard let user_id = custom["me"] as? String, let room_id = custom["room_id"] as? String else {
                completionHandler()
                return
            }

            // secutiry elements
            guard let token = String(data: Keychain.load("push_token")!, encoding: .utf8),
                let uuid = String(data: Keychain.load("UUID")!, encoding: .utf8) else {
                completionHandler()
                return
            }

            let key = Constantes.KEY
            let chats = Chats()

            // this executes an http request
            chats.sendMessage(token: token, uuid: uuid, key: key!, message: messageUser, user_id: user_id, room_id: room_id)
        }

    default: break
    }
    completionHandler()

}

}

在上一个函数中，我执行一个http请求来回复推送通知中的消息。真正的问题发生在我在通知中回复消息并点击发送按钮时，有时会执行http请求，有时则不会。我已经在我的应用程序的功能中添加了后台模式，实际上我从api成功接收通知，api正在发送值为'content-available'的1.最后，证书.pem在服务器中正常工作，所以。我错过了什么？

我只是遇到了这个问题并且没有线索为什么如果应用程序处于后台但我的快速回复有效，而不是当它被杀死时。然后我开始通过源代码查找内容，并在UNNotificationCenter：

中偶然发现了这一点

// The method will be called on the delegate when the user responded to the notification by opening the application, dismissing the notification or choosing a UNNotificationAction. The delegate must be set before the application returns from application:didFinishLaunchingWithOptions:.
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)(void))completionHandler

如果您在评论的最后部分阅读得很好，则表示必须在从application:didFinishLaunchingWithOptions:

返回之前设置代理人

这是我的错误所在。我在完成UNUserNotificationCenter.current().getNotificationSettings

时设置了委托

所以你要做的就是确保在UNUserNotificationCenter.current().delegate = self返回之前设置代理application:didFinishLaunchingWithOptions:

应用程序被杀或屏幕被锁定时未调用UNTextInputNotificationAction 3
