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，您可以在其中放置大学的课程，但事实是我要从json数据库获取日程安排，并且我想在15分钟前通知课程开始，但是我不知道为什么我的代码无法正常工作.

I want to set a local notification in xcode7, I'm developing a calendar where you can put your university's courses, the thing is that I'm getting the schedule from a json database and I want to notify 15 min before the class starts, but I do not know why my code is not working.

这是一个示例，我想在每个星期一的13:40重复通知.

This is an example where I want to repeat the notification every Monday at 13:40.

我只能设置日期和时间吗?还是也应该指定月份和年份?

Can I only set the day and the hour? or should I specify the month and the year too?

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)

推荐答案

**迅速的每周本地通知4

**Weekly Local notification for swift 4

let content = UNMutableNotificationContent() content.title = "LocalNotification" content.subtitle = "notify" content.body = "I am Text" content.categoryIdentifier = "alarm" content.badge = 1 content.sound = UNNotificationSound.default()

//配置重复日期.

var dateComponents = DateComponents() dateComponents.calendar = Calendar.current dateComponents.weekday = 3 dateComponents.hour = 13 dateComponents.minute = 10 // Create the trigger as a repeating event. let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true) // Create the request let uuidString = UUID().uuidString let request = UNNotificationRequest(identifier: uuidString, content: content, trigger: trigger) // Schedule the request with the system. let notificationCenter = UNUserNotificationCenter.current() notificationCenter.add(request) { (error) in if error != nil { // Handle any errors. print("************Error***************") } } }
