ios - how do I hide footer of all view controller witch attach with my navigation controller in swift project?

问题描述

I am working on swift project, which uses Xcode 9 and swift 4.1. I created one navigation viewcontroller and then created other view controller and attached with that that navigation viewcontroller.

so I got header and footer by default.so I have a two problems,

  1. Now I want a change a color of footer other than white but when I write any code for that It diminished behind footer and I don't see any color without white.How do I give any color to footer?

  2. If I am not able to give color to footer so I want to hide that footer using bellow code

    override func viewWillAppear(animated: Bool)
{
   self.navigationController?.navigationBarHidden = true
}

But by this color I am able to hide only header not a footer. so how do I hide footer using code so I created customise footer what I want.

How do I solve above problem in swift 4.1?

解决方案

我不知道您在这里所说的页脚是什么意思，因为默认情况下，当您将视图控制器嵌入导航控制器时，它不会显示任何页脚。您在那里做两件可能的事情：

  1. 您的导航控制器嵌入在 TabBarController 中
  2. 或者您已取消隐藏导航控制器的工具栏。

现在，如果您使用 TabBarController 作为导航控制器的父级，您可以简单地使用以下代码来隐藏页脚：

self.tabBarController?.tabBar.isHidden = true

如果您使用导航控制器的工具栏（默认情况下隐藏）。您可以使用以下代码来隐藏它：

navigationController?.setToolbarHidden(true, animated: false)

要更改工具栏的颜色，您可以简单地使用：

navigationController?.toolbar.barTintColor = .black
