NotificationCenter 的使用可以说是 iOS 开发中常见的一个小技巧。它是苹果的全局通知中心，可以在不同组件之间传递消息，而不需要它们直接引用对方。通过这个 Demo，你可以轻松地掌握如何发送、接收和通知。你可以通过[NSNotificationCenter defaultCenter]来访问它，理解发布/订阅模式：发布者发送通知，订阅者接收通知，极大地方便了模块间的解耦。通过postNotificationName:object:userInfo:方法发送通知，利用addObserver来监听并通知，简单方便。不用担心内存泄漏，因为removeObserver方法可以让你随时取消监听。通过这个 Demo，你能更好地理解如何在 iOS 项目中灵活运用 NotificationCenter，注意不要滥用，避免性能问题哦。
