Question

我正在使用Firebase发送远程消息，如下所示：

AppDelegate（伪代码）：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    FirebaseApp.configure()
    Messaging.messaging().delegate = self

    UNUserNotificationCenter.current().delegate = self
    UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) {granted, error in            
        let actionWithText = UNTextInputNotificationAction(identifier: "actionWithText", title: "Action with text", options: [.foreground], textInputButtonTitle: "Send", textInputPlaceholder: "Placeholder")
        let action = UNNotificationAction(identifier: "action", title: "Action without text", options: [.foreground])
        let category = UNNotificationCategory(identifier: "category", actions: [actionWithText, action], intentIdentifiers: [], options: [])

        UNUserNotificationCenter.current().setNotificationCategories([category])
    }

    application.registerForRemoteNotifications()

    return true
}

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    if response.actionIdentifier == "actionWithText" {
        if let textResponse = response as? UNTextInputNotificationResponse {
            let textResponse = textResponse.userText
        }
    }

    if response.actionIdentifier == "action" {
        print("action received")
    }

    completionHandler()
}

当应用程序在后台（仅在接听电话后处于活动状态的“电话”应用程序时）发送通知。

接收通知正常，我可以看到两个动作并进行选择。选择后，该应用程序将成为前台。但是，通知不会关闭。我尝试在多个地方（也在didReceive处理程序中）使用UNUserNotificationCenter.current().removeAllDeliveredNotifications()，但通知永不消失。在最近的iOS版本中，我发现removeAllDeliveredNotifications（或getDeliveredNotifications）在Stack Overflow上有很多问题。

我尝试删除.foreground作为选项，但这确实消除了该通知（选择一个动作之后）。但显然并没有使我的应用程序成为预期的功能。

您需要添加此方法

func didReceive(_ response: UNNotificationResponse, completionHandler completion: @escaping (UNNotificationContentExtensionResponseOption) -> Void) {

    if response.actionIdentifier == "Clear" {
        completion(.dismiss)
        print("Clear. It will dismiss the notification")
    }else if (response.actionIdentifier == "Next"){
        completion(.doNotDismiss)
        print("Next. It will not dismiss the notification")
    }
}

选择后，UNNotificationAction不会消失
