设置NavigationBar隐藏和显示

页面隐藏和显示navigation注意要使用setNavigationBarHidden(true, animated: true)方法，直接设置值，防止过于突兀。

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    self.navigationController?.setNavigationBarHidden(true, animated: true)
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    self.navigationController?.setNavigationBarHidden(false, animated: true)
}
