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.
