在函数中将日期转换为DateComponents，以在Swift 3中安排本地通知

import UserNotifications

func scheduleLocalNotification(date: Date) {
    let calendar = Calendar.current
    let components = calendar.dateComponents([.year, .month, .day, .hour, .minute, .second], from: date)
    
    let notificationContent = UNMutableNotificationContent()
    notificationContent.title = "本地通知标题"
    notificationContent.body = "本地通知内容"
    notificationContent.sound = UNNotificationSound.default
    
    let trigger = UNCalendarNotificationTrigger(dateMatching: components, repeats: false)
    let request = UNNotificationRequest(identifier: "LocalNotification", content: notificationContent, trigger: trigger)
    
    UNUserNotificationCenter.current().add(request) { (error) in
        if let error = error {
            print("添加本地通知失败：\(error.localizedDescription)")
        } else {
            print("本地通知添加成功")
        }
    }
}
