I want to specify a notification time in Swift LocalNotification

let myDateFormatter=NSDateFormatter()
myDateFormatter.locale=NSLocale(localeIdentifier: "ja_JP")
myDateFormatter.dateFormat="yyyy/MM/dd hh:mm"

let mySelectedDate: NSSstring=myDateFormatter.stringFromDate(sender.date)
dateField.text = mySelectedDate as String


UIAApplication.sharedApplication().cancelAllLocalNotifications();
let setting = UIUserNotificationSettings (forTypes: [.Sound, .Alert], categories:nil)
UIAApplication.sharedApplication().registerUserNotificationSettings(setting)
let notification = UILocalNotification()
notification.fireDate=myDateFormatter
notification.timeZone=NSTimeZone.defaultTimeZone()
notification.alertBody="Notification"
notification.alertAction="OK"
notification.soundName = UILocalNotificationDefaultSoundName
UIAApplication.sharedApplication().scheduleLocalNotification(notification);
