Question

我在我的应用中有提醒。其中我每天都会重复通知。现在可以在我的通知中心看到多个通知。由于它的可操作通知用户可以点击＆＃34;是＆＃34;或＆＃34;否＆＃34;。

我聆听它如下：

import Foundation
import UserNotifications
import UserNotificationsUI


class NotificationSetup: NSObject, UNUserNotificationCenterDelegate
{

    let requestIdentifier = "SampleRequest"
    let salahTimeArr =
        [

            [ "salahName": "Fajar", "time" : DateComponents.init( hour: 7, minute: 0 )],
            [ "salahName": "Zuhar", "time" : DateComponents.init( hour: 14, minute: 0 )],
            [ "salahName": "Asar", "time" : DateComponents.init( hour: 18, minute: 0 )],
            [ "salahName": "Maghrib", "time" : DateComponents.init( hour: 19, minute: 30 )],
            [ "salahName": "Isha", "time" : DateComponents.init( hour: 22, minute: 0 ) ]

    ]

    //============================================================

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

        center.requestAuthorization(options: [.alert, .sound])
        {
            (granted, error) in

            let actionYes = UNNotificationAction(identifier: "yes", title: "Yes", options: [])

            let actionNo = UNNotificationAction(identifier: "no", title: "No", options: [])

            let category = UNNotificationCategory(identifier: "SalahOfferedActionableNotification", actions: [actionYes, actionNo], intentIdentifiers: [], options: [])

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

        }

    }


    //----------------------------------

    func setNotifications()
    {

        self.createNotificationCategory()


        if ( UserDefaults.standard.bool(forKey: "isNotificationSet") == false )
        {

            for salahDict in salahTimeArr
            {

                print(salahDict["salahName"])

                let content = UNMutableNotificationContent()
                content.title = "Did you offer"
                content.subtitle = salahDict["salahName"] as! String
                content.body = "Its Fard!"
                content.sound = UNNotificationSound.default()
                content.categoryIdentifier = "SalahOfferedActionableNotification"

                //------------------------

                let date = salahDict["time"] as! DateComponents

                let trigger = UNCalendarNotificationTrigger.init(dateMatching: date, repeats: true)


                let request = UNNotificationRequest(identifier: requestIdentifier, content: content, trigger: trigger)

                //------------------------

                let notificationSingletonObj = UNUserNotificationCenter.current()
                notificationSingletonObj.delegate = self

                //------------------------

                notificationSingletonObj.add(request)
                {
                    (error) in

                    if (error != nil)
                    {
                        print(error?.localizedDescription)
                    }
                }
            }
            UserDefaults.standard.set( true, forKey: "isNotificationSet" )
        }
    }

    //============================================================

    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void)
    {
        let salahName = response.notification.request.content.subtitle
        let date = response.notification.date

        if response.actionIdentifier == "yes"
        {
            print("User tapped 'Yes' button on notification for Salah: \(salahName)")

            UserDefaults.standard.set( true, forKey: salahName )

            Calculation().addSalah(forSalah : salahName, offered: 1 )

            userDefaults.set( Date(), forKey: "dataCapturedForDate")
        }

    }


}

我想阅读通知日期（触发日期）。我找到了以下

let date = response.notification.date

但正如苹果文档所说它支持iOS 10＆amp;后来。但是我想要支持iOS7。

请参阅通知中心图像以清楚地理解。我有相同的标题，描述＆amp;所有通知信息类似。我想检测用户点击的通知。天气是星期一的通知或星期二的通知。天气是＆＃34; A＆＃34;或＆＃34; B＆＃34;

Answer 1

fireDate属性UILocalNotification。你可以使用它。另外，要支持iOS7，您需要使用UILocalNotification代替UNUserNotificationCenterDelegate

发起本地通知

let localNotification = UILocalNotification()
let fireDate = Date()
localNotification.fireDate = fireDate
localNotification.alertBody = "Your alert message"
localNotification.repeatInterval = .day
UIApplication.shared.scheduleLocalNotification(localNotification)

在您的app delegate

中

func application(_ application: UIApplication, didReceive notification: UILocalNotification) {
  notification.fireDate
}
