用户在swift中设置通知的时间

import UIKit class MyView: UIViewController { @IBOutlet var mySwitch: UISwitch! @IBOutlet var myDatePicker: UIDatePicker! func datePicker() { myDatePicker.datePickerMode = UIDatePickerMode.Date } override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. datePicker() } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } @IBAction func switchPressed(sender: AnyObject) { if mySwitch.on{ var localNotification:UILocalNotification = UILocalNotification() localNotification.alertAction = "Open App" localNotification.alertBody = "Here is your notification at 7:00 AM" localNotification.fireDate = myDatePicker.date localNotification.repeatInterval = NSCalendarUnit.CalendarUnitDay UIApplication.sharedApplication().scheduleLocalNotification(localNotification) } else { var localNotification:UILocalNotification = UILocalNotification() localNotification.alertAction = "Open App" localNotification.alertBody = "This notification should not appear" localNotification.fireDate = NSDate(timeIntervalSinceNow: 999999999999) IApplication.sharedApplication().scheduleLocalNotification(localNotification) } } }

在您的项目中创build一个新的Swift Source文件来放置您的扩展

 import Foundation public extension NSDate { func xDays(x:Int) -> NSDate { return NSCalendar.currentCalendar().dateByAddingUnit(.CalendarUnitDay, value: x, toDate: self, options: nil)! } var day: Int { return NSCalendar.currentCalendar().components(NSCalendarUnit.CalendarUnitDay, fromDate: self).day } var month: Int { return NSCalendar.currentCalendar().components(NSCalendarUnit.CalendarUnitMonth, fromDate: self).month } var year: Int { return NSCalendar.currentCalendar().components(NSCalendarUnit.CalendarUnitYear, fromDate: self).year } var fireDate: NSDate { return NSCalendar.currentCalendar().dateWithEra(1, year: year, month: month, day: day, hour: 7, minute: 0, second: 0, nanosecond: 0)! } }

如果你已经有了UIDatePicker ，你只需要从中获取date属性并使用它来设置fireDate 。
