how to change Navigation shadow color when changed mode in swift 5?-CodePudding

navigationController?.navigationBar.layer.shadowColor = ColorPalette.navigationBarShadowColor.cgColor

set color according to mode.

class ColorPalette : NSObject {

static var navigationBarShadowColor: UIColor {

    return UIColor { (traits) -> UIColor in
        //dark: Black // light: grey16
        return traits.userInterfaceStyle == .dark ?
        UIColor.black : UIColor(hex: "dbdbdc")
    }
}

}

CodePudding user response：

Add this in AppDelegate

UINavigationBar.appearance().shadowColor = UITraitCollection.current.userInterfaceStyle == .light ? UIColor(named: "light_color") : UIColor(named: "dark_color")

CodePudding user response：

remove navigationBar shadow

self.navigationController?.navigationBar.shadowImage = UIImage()

if iOS 13

self.navigationController?.navigationBar.standardAppearance.shadowColor = UIColor.black

CodePudding user response：

override func traitCollectionDidChange(_ previousTraitCollection: UITraitCollection?) {
      super.traitCollectionDidChange(previousTraitCollection)
      self.navigationController?.navigationBar.standardAppearance.shadowColor = UIColor.black.cgColor 
  }

we are using this and it is working but we want only one class we have to add this type of code like AppDelegate or some other classes .
