如何实现多个本地通知而不是swift 3的单个通知

Question

我使用单一通知,这是我的代码:这是用于注册本地通知>>>

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

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

这个函数来安排本地通知>>>

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()
}

现在我如何使用这个代码与iOS 10的多个本地通知和不同的时间谢谢你.

Answer 1

您可以func scheduleLocal()使用不同的多次呼叫dateComponents在不同的日期安排.或者,您可以将一组日期传递给此函数并运行循环以根据这些日期安排通知.

只需确保您在UNNotificationRequest(identifier:, content:, trigger:)函数中传递的标识符 对于每个通知都是不同的.

希望这可以帮助.:)

Answer 2

为每个通知使用不同的请求标识符(否则您只能看到最后一个通知).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.
