问题描述

我有一个通用应用程序，在 iPad 版本上我使用 UISplitViewController 创建一个类似于邮件应用程序的界面.

I have a universal app, and on the iPad version I'm using UISplitViewController to create an interface similar to the Mail app.

我在推送新的 Detail 视图时遇到了麻烦，因此我决定使用 UINavigationController 以便可以根据需要推送和弹出视图.但是，我不想使用导航视图或工具栏.但是无论我做什么，我都无法隐藏导航栏.

I was having trouble pushing new Detail views, so I decided to use a UINavigationController so I could just push and pop views as needed. However, I do not want to use the navigation view or a toolbar. But no matter what I do, I can't hide the navigation bar.

我尝试在 IB 中取消选中显示导航栏"，我也尝试过设置:

I've tried unchecking "Shows Navigation Bar" in IB, and I've also tried setting:

[self.navigationController setNavigationBarHidden:YES];

在 viewDidLoad/viewDidAppear/viewWillAppear 中.我还在将要推送的每个视图中都进行了尝试.没有任何效果.

in the viewDidLoad/viewDidAppear/viewWillAppear. I've also tried it in each of the views that will be pushed. Nothing works.

这里有什么我遗漏的吗?是否可以有一个没有工具栏或导航栏的 UINavigationController?

Is there something I'm missing here? Is it possible to have a UINavigationController without a toolbar or navigation bar?

推荐答案

你应该能够做到以下几点:

You should be able to do the following:

self.navigationController.navigationBar.isHidden = true //Swift 5

self.navigationController(显然)是 UINavigationController 的一个实例.似乎对我有用，但我只是在发布之前对其进行了简单的测试.

where self.navigationController is (obviously) an instance of UINavigationController. Seems to work for me, but I only briefly tested it before posting this.
