导读：UILocalNotification已被折旧,因此我想将我的代码更新为UserNotification框架： let alertDays = 3.0let alertSeconds = alertDays * 24.0 * 60.0 * 60.0let localNotification:UILocalNotification = UILocalNotification()localNotification.alertAction =

UILocalNotification已被折旧,因此我想将我的代码更新为UserNotification框架：

let alertDays = 3.0
let alertSeconds = alertDays * 24.0 * 60.0 * 60.0

let localNotification:UILocalNotification = UILocalNotification()

localNotification.alertAction = "Reminder"
localNotification.alertTitle = "Reminder Title"
localNotification.alertBody = "Reminder Message"
localNotification.fireDate = Foundation.Date(timeIntervalSinceNow: alertSeconds)
localNotification.repeatInterval = .day            
UIApplication.shared().scheduleLocalNotification(localNotification)

在等待初始通知后,如何使用UserNotification框架设置类似的每日或每小时重复？

let alertDays = 3.0
let alertSeconds = alertDays * 24.0 * 60.0 * 60.0

let content: UNMutableNotificationContent = UNMutableNotificationContent()

content.title = "Reminder Title"
content.subtitle = "Reminder Subtitle"
content.body = "Reminder Message"

let calendar = Calendar.current

let alarmTime = Foundation.Date(timeIntervalSinceNow: alertSeconds)
let alarmTimeComponents = calendar.components([.day,.hour,.minute],from: alarmTime)

let trigger = UNCalendarNotificationTrigger(dateMatching: alarmTimeComponents,repeats: true)

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

UNUserNotificationCenter.current().add(request)
    {
        (error) in // ...
    }

看起来这似乎不受支持,但为了制定解决方法,您可以使用：

let alertDays = 3.0
let daySeconds = 86400
let alertSeconds = alertDays * daySeconds

let content: UNMutableNotificationContent = UNMutableNotificationContent()

content.title = "Reminder Title"
content.subtitle = "Reminder Subtitle"
content.body = "Reminder Message"

let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: (alertSeconds),repeats: false)

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

UNUserNotificationCenter.current().add(request)
{
    (error) in // ...
}

与didReceive(_:withContentHandler:)结合使用,您可以使用：

let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: (daySeconds),repeats: false)

我知道这不是最佳的,但它应该不使用已弃用的类/方法.您使用重复：false,因为您在用户收到通知并创建新通知之前拦截通知.此外,如果您处理多个通知,则可以将它与UNNotificationAction和UNNotificationCategory结合使用.
