Swift4 如何优雅的使用通知NotificationCenter

使用示例:

// 发送通知
NotificationCenter.default.post(name: NSNotification.Name.EndTopicSuccessNoti, object: nil)

// 添加通知监听
NotificationCenter.default.addObserver(self, selector: #selector(endTopicAction), name: NSNotification.Name.EndTopicSuccessNoti, object: nil)

extension Notification.Name {
    /// 结束会话成功通知
   static let EndTopicSuccessNoti = Notification.Name(rawValue:"EndTopicSuccess")
}

使用RxSwift

NotificationCenter.default.rx.notification(Notification.Name.EndTopicSuccessNoti, object: nil).subscribe(onNext: { (notification) in
  ...
}).disposed(by: disposeBag)
