ios – NSNotificationCenter addObserver在Swift中调用私有方法

我使用addObserver API接收通知：

NsnotificationCenter.defaultCenter().addObserver(self,SELEctor: "methodOFReceivedNotication:",name:"NotificationIdentifier",object: nil)

我的方法是：

func methodOFReceivedNotication(notification: Nsnotification){
//Action take on Notification
}

是的,它的作品！
但是当我将@L_861_1@methodOFReceivedNotication更改为private时：

private func methodOFReceivedNotication(notification: Nsnotification){
//Action take on Notification
}

xCode向我发送错误：无法识别的选择器发送到实例

当目标是自我时,如何调用私有方法？我不想将methodOFReceivedNotication方法暴露给任何其他方法.

dynamic private func methodOFReceivedNotication(notification: Nsnotification){
    //Action take on Notification
}

@objc private func methodOFReceivedNotication(notification: Nsnotification){
    //Action take on Notification
}
