    content.title = "iOS10.0"
    content.body = "Hello Buddy"
    content.sound = UNNotificationSound.default()
    // Deliver the notification in five seconds.
    let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 5, repeats: false)
    let request = UNNotificationRequest.init(identifier: "FiveSecond", content: content, trigger: trigger)
    // Schedule the notification.

你必须实现一个 UNUserNotificationCenter 的委托(delegate)来告诉系统你想在应用程序运行时显示通知。在此处查看示例:https://github.com/jerbeers/DemoLocalNotification
