推荐答案

我相信你试图在 firstVC 中隐藏 navigationBar 并在 secondVC 中显示它代码>.

I believe you trying to hide navigationBar in firstVC and show it in secondVC.

在您的 firstVC 中尝试以下方法，并确保您使用 navigationController 嵌入了您的 firstVC.

Try following method into your firstVC and make sure you embedded your firstVC with navigationController.

您的 storyBoard 流程布局应如下所示...

Your storyBoard flow layout should be look like below...

在 firstVC 中实现以下方法.

override func viewWillAppear(_ animated: Bool) {

    self.navigationController?.setNavigationBarHidden(true, animated: true)
}

override func viewWillDisappear(_ animated: Bool) {

    self.navigationController?.setNavigationBarHidden(false, animated: true)   
}

输出:更新
