ios - 时间增加一天后不会发送本地通知

Question

我正在创建一个应用程序，该应用程序会在用户通过应用程序界面指定的时间发送每日本地通知。

在测试期间，我安排了 20 条每日本地通知，覆盖 20 天。在最后一天，用户可以点击按钮来安排另外 20 个事件。

当我运行应用程序时，它仅发送第一个通知。其余的通知永远不会发送。如何修复我的代码以使时间增加一天？

// Function that schedules the 20 notifications in advance so each one is delivered every day
func scheduleNotif() {
// Notification #1
    let content = UNMutableNotificationContent()
    content.title = "Good Morning \(name)!"
    content.body = sendMessage()
    content.sound = UNNotificationSound.default()

// Time in which notification will fire
    let dailyTime = Calendar.current.dateComponents([.hour, .minute,], from: timePick.date)
    let trigger = UNCalendarNotificationTrigger(dateMatching: dailyTime, repeats: false)

// The identifier for the notification so that it is distinguishable from others in code
    let identifier = "Positive Message"

    // Requesting for notification to be delivered
    let request = UNNotificationRequest(identifier: identifier, content: content, trigger: trigger)
    let center = UNUserNotificationCenter.current()
    center.add(request) { (error : Error?) in
        if let theError = error {
            print(theError.localizedDescription)

        }

    }
// Notification #2

Answer 1

您将通知设置得很好。但请重新考虑您的代码。

就像在某些函数中尝试这样使用。我写的不是你的代码，只是一个例子来帮助你理解

  func someFunction() {
        for i in 1..<21 {
        var notificationR = UILocalNotification()
        notificationR = setUpNotification(notificationR)
        notificationR.fireDate = Date.init(timeIntervalSinceNow: Double(i))
        notificationR = publishLocalNotification(notificationR)
    }
}


func setUpNotification(_ notification: UILocalNotification) -> UILocalNotification {
    notification.alertBody = "Positive message"
    notification.soundName = UILocalNotificationDefaultSoundName
    notification.timeZone = TimeZone.current
    notification.repeatInterval = NSCalendar.Unit.day
    return notification
}


func publishLocalNotification(_ notification: UILocalNotification) -> UILocalNotification {
    UIApplication.shared.applicationIconBadgeNumber = 0
    UIApplication.shared.scheduleLocalNotification(notification)
    return notification
}
