Navigation Bar

Navigation bars for iOS are implemented using the built-in UIKit component UINavigationBar, however they should be configured using the Thumbprint decorator method NavigationBar.configure(_:appearance:content:) to apply one of the standard Thumbprint navigation bar styles.

There are three standard navigation bar appearances. In addition, custom themes can be defined by calling the NavigationBar.Appearance constructor directly.

There are two standard content styles. The content style defines how foreground content such as text should be displayed.

Dark content style to be used on a navigation bar with a light background.

var isTranslucent: Bool

var backgroundImage: UIImage?

var titleTextAttributes: [NSAttributedString.Key: Any]?

If no foreground color is specified, will default to the content style's foreground color.

var largeTitleTextAttributes: [NSAttributedString.Key: Any]?

If no foreground color is specified, will default to the content style's foreground color.
