When developing in swift 3 I was used to write:
UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName: UIColor.orange]
putting this in AppDelegate would change all the UINavbars' title color to orange.
Now I want to do the same with Swift 4 and iOS 11.
App delegate swift 4.2
UINavigationBar.appearance().barTintColor = UIColor.white
UINavigationBar.appearance().tintColor = UIColor(hex: 0xED6E19)
UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor : UIColor(hex: 0xED6E19)]
Swift 4 implementation for both large and regular titles:
extension UINavigationController {
func setTitleForgroundTitleColor(_ color: UIColor) {
self.navigationBar.titleTextAttributes = [NSAttributedStringKey(rawValue: NSAttributedStringKey.foregroundColor.rawValue): color]
}
func setLargeTitleColor(_ color: UIColor) {
self.navigationBar.largeTitleTextAttributes = [NSAttributedStringKey(rawValue: NSAttributedStringKey.foregroundColor.rawValue): color]
}
func setAllTitleColor(_ color: UIColor) {
setTitleForgroundTitleColor(color)
setLargeTitleColor(color)
}
}
You can change the navigation bar title color by using this code
navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.white]
Swift 4.2
fileprivate func convertToOptionalNSAttributedStringKeyDictionary(_ input: [String: Any]?) -> [NSAttributedString.Key: Any]? {
guard let input = input else { return nil }
return Dictionary(uniqueKeysWithValues: input.map { key, value in (NSAttributedString.Key(rawValue: key), value)})
}
Usage
// Set Navigation bar Title color
UINavigationBar.appearance().titleTextAttributes = convertToOptionalNSAttributedStringKeyDictionary([NSAttributedString.Key.foregroundColor.rawValue : UIColor.white])
For Swift 5 if Someone is Looking around like I was :
self.navigationController?.navigationBar.largeTitleTextAttributes = [NSAttributedString.Key.foregroundColor : UIColor(displayP3Red: 84/255, green: 93/255, blue: 118/255, alpha: 1)]
