notifications - 如何实现多个本地通知而不是Swift 3的单个通知

Question

我已经使用了单个通知，这是我的代码:
这是用于注册本地通知的>>>

    func registerLocal() {
    let center = UNUserNotificationCenter.current()

    center.requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
        if granted {
            print("Yay!")
        } else {
            print("D'oh")
        }
    }
}

并且此功能可以安排本地通知>>>

func scheduleLocal() {
    registerCategories()

    let center = UNUserNotificationCenter.current()

    // not required, but useful for testing!
    center.removeAllPendingNotificationRequests()

    let content = UNMutableNotificationContent()
    content.title = "good morning"
    content.body = "ttt123"
    content.categoryIdentifier = "alarm"
    content.userInfo = ["customData": "fizzbuzz"]
    content.sound = UNNotificationSound.default()

    var dateComponents = DateComponents()
    dateComponents.hour = 23
    dateComponents.minute = 18
    let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)

    let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger)
    center.add(request)
}

func registerCategories() {
    let center = UNUserNotificationCenter.current()
    center.delegate = self

    let show = UNNotificationAction(identifier: "show", title: "Tell me more…", options: .foreground)
    let category = UNNotificationCategory(identifier: "alarm", actions: [show], intentIdentifiers: [])

    center.setNotificationCategories([category])
}

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    // pull out the buried userInfo dictionary
    let userInfo = response.notification.request.content.userInfo

    if let customData = userInfo["customData"] as? String {
        print("Custom data received: \(customData)")

        switch response.actionIdentifier {
        case UNNotificationDefaultActionIdentifier:
            // the user swiped to unlock; do nothing
            print("Default identifier")

        case "show":
            print("Show more information…")
            break

        default:
            break
        }
    }

    // you need to call the completion handler when you're done
    completionHandler()
}

现在如何在iOS 10和不同时间的多个本地通知中使用此代码
谢谢你 。

为每个通知使用不同的请求标识符(否则，您只会看到最后一个通知)。
在上面的示例中，确保请求标识符“UUID()。uuidString”包含每个通知请求的唯一值。
