增加时间一天后，本地通知将不会发送

Question

我正在创建一个应用程序，该应用程序在用户通过应用程序界面指定的时间提供每日本地通知。

在测试过程中，我安排了20个每日本地通知20天。在最后一天，用户可以点击按钮安排20多个。

当我运行该应用程序时，它只发送第一个通知。剩下的通知永远不会被发送。我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()

// 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()

Answer 1

您可以设置您的通知罚款。但请重新考虑你的代码。

就像在某些功能中试图使用这样。我不写你的代码只是一个例子，以帮助您了解

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 
}
