如何在swift中设置每周本地通知

Question

我的代码有问题。

我想在xcode7中设置本地通知，我正在开发一个日历，您可以放置​​您的大学课程，事情是我从json数据库获取日程安排，并且我想在15分钟前通知该课程开始，但我不知道为什么我的代码不工作。

这是一个例子，我想在每个星期一13:40重复通知。

我只能设置日期和时间吗？或者我应该指定月份还是年份？

var dateComp:NSDateComponents = NSDateComponents() 

    dateComp.day = 01; 
    dateComp.hour = 13; 
    dateComp.minute = 40; 
    dateComp.timeZone = NSTimeZone.systemTimeZone() 

    var calender:NSCalendar = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)! 
    var date:NSDate = calender.dateFromComponents(dateComp)! 

    let notification = UILocalNotification() 
    notification.fireDate = date 
    notification.alertBody = "Swipe to unlock" 
    notification.alertAction = "You've got a class soon!" 
    notification.soundName = UILocalNotificationDefaultSoundName 
    notification.userInfo = ["CustomField1": "w00t"] 
    notification.repeatInterval = NSCalendarUnit.WeekOfYear 

    UIApplication.sharedApplication().scheduleLocalNotification(notification)

请检查该功能

func setLNotification(weekDay:Int , hour:Int, min:Int, second:Int, alertBody:String, type:String, isRepeate:Bool){ 
    let calender = NSCalendar(identifier: NSCalendarIdentifierGregorian) 
    let dateComp: NSDateComponents? 
    let components: NSDateComponents = NSDateComponents() 

    if weekDay > 0{ 
     components.setValue(-50, forComponent: NSCalendarUnit.Year) 

     let previousDate = NSCalendar.currentCalendar().dateByAddingComponents(components, toDate: NSDate(), options: NSCalendarOptions(rawValue: 0))! 
     dateComp = calender?.components([.Year,.WeekOfMonth,.Month], fromDate: previousDate) 
     dateComp?.hour = hour 
     dateComp?.minute = min 
     dateComp?.second = second 
     dateComp?.weekday = weekDay 
    }else{ 
     components.setValue(hour, forComponent: NSCalendarUnit.Hour) 
     components.setValue(min, forComponent: NSCalendarUnit.Minute) 
     components.setValue(second, forComponent: NSCalendarUnit.Second) 
     let notifiDate = NSCalendar.currentCalendar().dateByAddingComponents(components, toDate: NSDate(), options: NSCalendarOptions(rawValue: 0))! 
     dateComp = calender?.components([.Year,.Month,.Day,.Hour,.Minute,.Second], fromDate: notifiDate) 
    } 

    let notification = UILocalNotification() 
    if isRepeate == true{ 
     notification.repeatInterval = NSCalendarUnit.WeekOfYear 
     notification.repeatCalendar = calender 
    } 
    notification.fireDate = calender?.dateFromComponents(dateComp!) 
    notification.alertBody = alertBody 
    notification.userInfo = ["day":"\(weekDay)","type":"\(type)"] 

    UIApplication.sharedApplication().scheduleLocalNotification(notification) 
}
