使用iOS13.4、XCode11.4、Swift5.2、

您如何设置将在每个工作日（即周一至周五，但不是周六和周日）触发的本地通知？

我尝试了不同的日历组件设置，但没有成功解决工作日问题。

这是我到目前为止所做的......

如果警报需要在特定日期：

Calendar.current.dateComponents([.day, .month, .year, .hour, .minute, .second], from: notificationDate)

如果闹钟需要每天重复：

Calendar.current.dateComponents([.hour, .minute], from: notificationDate)

如果闹钟需要在特定工作日重复：

Calendar.current.dateComponents([.weekday, .hour, .minute], from: notificationDate)

等等

但是您如何设置几个工作日（例如每个工作日周一到周五）？

这是我的精确 notificationDate 示例的代码：

import UIKit

class MyViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        let content = UNMutableNotificationContent()
        content.title = "My Notification Title"
        content.categoryIdentifier = UUID().uuidString
        var notificationIdentifier = "23224-23134-234234"
        var notificationDate = Date(timeInterval: 30, since: Date())
        let notificationTriggerKind = Calendar.current.dateComponents([.day, .month, .year, .hour, .minute, .second], from: notificationDate)
        let notificationTrigger = UNCalendarNotificationTrigger(dateMatching: notificationTriggerKind, repeats: false)
        let notificationRequest = UNNotificationRequest(identifier: notificationIdentifier, content: content, trigger: notificationTrigger)
        let notificationCenter = UNUserNotificationCenter.current()
        notificationCenter.delegate = self
        notificationCenter.add(notificationRequest) {(error) in if let error = error { print("error: \(error)") } }
    }
}

extension MyViewController: UNUserNotificationCenterDelegate {

    // kicks in when App is running in Foreground (without user interaction)
    func userNotificationCenter(_ center: UNUserNotificationCenter,
            willPresent notification: UNNotification,
            withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

        // ...do your custom code...
        completionHandler([.alert, .sound])
    }

    // kicks in when App is running in Foreground or Background
    // (AND App is open) AND user interacts with notification
    func userNotificationCenter(_ center: UNUserNotificationCenter,
        didReceive response: UNNotificationResponse, withCompletionHandler
        completionHandler: @escaping () -> Void) {

        // ... do your custom code ....
        return completionHandler()
    }
}

你走的很好。

要做到这一点，您需要为每一天安排一个通知。

检查这个例子：

  • 创建和扩展日期以获取特定日期的小时、分钟和秒
        extension Date {
        public func getDateComponents() -> DateComponents {
               let dateComponents = Calendar.current.dateComponents([ .hour, .minute, .second], from: self)

               return dateComponents
           }
    }
  • 或者直接创建一个日期组件：
    var dateComponents = DateComponents()
    dateComponents.hour = 9
    dateComponents.minutes = 10
    dateComponents.weekDay = 1
  • 然后检查从星期一（2）到星期五（6）的花费天数并迭代一组工作日以创建每天的特定通知并重复。
    let workDays = 2...6
            for day in workDays {
                var dateComponents = date.getDateComponents()
                dateComponents.weekday = day

                let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: repeats)

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

                self.notificationCenter.add(request) { (error) in
                    if let error = error {
                    }
                }
            }
