问题描述

我有一个 UINavigationController，它链接到一个设置为 RootController 的 ViewController.我启用了 UINavigationBar 并在其中放置了 3 个 UIViews，每个 UIViews 都有一个 UIButton.理想情况下，我想让 UINavigationBar 完全不可见，但我也愿意将颜色设置为我的 ViewController 的背景颜色.我正在快速工作，我尝试过诸如

I have a UINavigationController that is Linked to a ViewController that is set as RootController. I have enabled the UINavigationBar and put 3 UIViews each with a UIButton inside. Ideally I would like to make the UINavigationBar completely invisible, but I would also settle for setting the color to the background color of my ViewController. I am working in swift and I have tried things like

self.navigationBar.setBackgroundImage(UIImage(), forBarMetrics: UIBarMetrics.Default)
self.navigationBar.shadowImage = UIImage()
self.navigationBar.translucent = true

但是没有任何变化.有没有正确的方法来做到这一点?

However nothing changes. Is there a correct way to do this?
