斯威夫特3

UINavigationBar.appearance().barTintColor = UIColor(colorLiteralRed: 51/255, green: 90/255, blue: 149/255, alpha: 1)

这将设置你的导航栏颜色像Facebook栏颜色:)

在Swift 2中

在导航栏中更改颜色，

navigationController?.navigationBar.barTintColor = UIColor.whiteColor()

在项目导航栏中更改颜色，

navigationController?.navigationBar.tintColor = UIColor.blueColor()

or

navigationController!.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.blueColor()]

更新为Swift 3, 4, 4.2, 5+

// setup navBar.....
UINavigationBar.appearance().barTintColor = .black
UINavigationBar.appearance().tintColor = .white
UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]
UINavigationBar.appearance().isTranslucent = false

斯威夫特4

UINavigationBar.appearance().barTintColor = .black
UINavigationBar.appearance().tintColor = .white
UINavigationBar.appearance().titleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.white]
UINavigationBar.appearance().isTranslucent = false

Swift 4.2, 5+

UINavigationBar.appearance().barTintColor = .black
UINavigationBar.appearance().tintColor = .white
UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
UINavigationBar.appearance().isTranslucent = false

如果你想使用大标题，添加这一行:

UINavigationBar.navigationBar.prefersLargeTitles = true

在故事板上执行此操作(接口构建器检查器)

在IBDesignable的帮助下，我们可以为UINavigationController添加更多的界面生成器检查器选项，并在故事板上调整它们。首先，将以下代码添加到项目中。

@IBDesignable extension UINavigationController {
    @IBInspectable var barTintColor: UIColor? {
        set {
            guard let uiColor = newValue else { return }
            navigationBar.barTintColor = uiColor
        }
        get {
            guard let color = navigationBar.barTintColor else { return nil }
            return color
        }
    }
}

然后在storyboard上简单地设置导航控制器的属性。

这个方法也可以用于管理故事板中导航栏文本的颜色:

@IBInspectable var barTextColor: UIColor? {
  set {
    guard let uiColor = newValue else {return}
    navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor: uiColor]
  }
  get {
    guard let textAttributes = navigationBar.titleTextAttributes else { return nil }
    return textAttributes[NSAttributedStringKey.foregroundColor] as? UIColor
  }
}

Swift 4, iOS 12和Xcode 10更新

只需在viewDidLoad()中放入一行

navigationController?.navigationBar.barTintColor = UIColor.red

UINavigationBar.appearance().barTintColor
