swift iOS localNotifications

Question

我想设置特定时间的本地通知，例如：04:30 Am Everyday，但我无法弄明白。我是iOS开发的新手，所有localNotifications教程都只包括fireDate = NSDate（）

谢谢！

Answer 1

在您希望触发本地通知的函数中尝试此代码：

let calendar = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)
let date = NSDate()
let dateComponents = calendar!.components([NSCalendarUnit.Day, NSCalendarUnit.WeekOfMonth, NSCalendarUnit.Month,NSCalendarUnit.Year,NSCalendarUnit.Hour,NSCalendarUnit.Minute], fromDate:date)
dateComponents.hour = 4
dateComponents.minute = 30
let notification = UILocalNotification()
notification.alertAction = "Title"
notification.alertBody = "Fire Fire Fire :v"
notification.repeatInterval = NSCalendarUnit.WeekOfYear
notification.fireDate = calendar.dateFromComponents(dateComponents)
UIApplication.sharedApplication().scheduleLocalNotification(notification)

请记住将此代码放在AppDelegate中：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {   
    application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [.Sound, .Badge, .Alert], categories: nil))
    return true
  }
