Swift- 在用户选择的时间推送通知

Question

如何让用户使用日期选择器选择时间，然后向用户发送本地通知？

Answer 1

这是一个简单的代码，用于在 swift 中安排本地通知：

let calendar: NSCalendar = NSCalendar.currentCalendar()

let fireDateOfNotification: NSDate = //The date which was picked from the picker

var notification = UILocalNotification()
notification.timeZone = NSTimeZone.localTimeZone()
notification.alertBody = "ALERT STRING"
notification.soundName = UILocalNotificationDefaultSoundName
notification.fireDate = fireDateOfNotification
notification.userInfo = ["UUID": "NotificationID"] //id for the local notification in case you want to cancel it

UIApplication.sharedApplication().scheduleLocalNotification(notification)

如果您想取消本地通知，您应该使用以下功能：

func cancelLocalNotificationsWithUUID(uuid: Int) {
        for item in UIApplication.sharedApplication().scheduledLocalNotifications {
            let notification = item as! UILocalNotification
            if let notificationUUID = notification.userInfo?["UUID"] as? Int {

                if notificationUUID == uuid {
                    UIApplication.sharedApplication().cancelLocalNotification(notification)
                }

            }
        }
    }

希望对您有所帮助。
