如何更改导航标题的颜色

Question

我正在尝试更改导航标题的颜色。如何在不在 AppDelegate 文件的 didFinishLaunchingWithOptions 方法中更改导航标题的颜色。

  var viewModel: SignUpViewModel? {
        didSet {
            viewModel?.viewDelegate = self
            title = "Sign Up"
            
        }
    }

Answer 1

您可以通过设置标题文本属性来更改导航栏标题颜色

    navigationController?.navigationBar.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.blue]

您可以通过设置色调颜色来更改导航栏按钮的颜色

navigationController?.navigationBar.tintColor = UIColor.blue

Answer 2

public var navigationBarColor = UIColor() {
                didSet {
                    UINavigationBar.appearance().barTintColor = UIColor(red: 234.0/255.0, green: 46.0/255.0, blue: 73.0/255.0, alpha: 1.0)
                    UINavigationBar.appearance().tintColor = UIColor.white
                    UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key
        .foregroundColor : UIColor.white]
                }
            }
