We are playing video in an AVPlayerViewController. The video contains subtitles, and when the user enters the AVMediaSelectionViewController in order to select a subtitle language, the Done button is completely invisible because it is a white font on a white background.

Does anyone know of a way to change the font color on this button?

Hi

Were you able to find answer to this question? I have tried numerous things including UINavigationBar appearance, extending UINavigationController none of which unfortunately work.

Let me know if you were able to find a solution.

Hi @seanmp

I was able to update the navigation bar if the AVMediaSelectionTableViewController using an extension class of UINavigationController. Please see code used below:

Code Block open override func viewDidLayoutSubviews() {
				let subtitleViewController: AnyClass? = NSClassFromString("AVMediaSelectionTableViewController")
				for childVC in self.viewControllers {
						if let subtitleViewController = subtitleViewController, childVC.isKind(of: subtitleViewController) {
								var normalTitleTextAttributes = childVC.navigationItem.rightBarButtonItem?.titleTextAttributes(for: .normal)
								var highlightedTitleTextAttributes = childVC.navigationItem.rightBarButtonItem?.titleTextAttributes(for: .highlighted)
								var disabledTitleTextAttributes = childVC.navigationItem.rightBarButtonItem?.titleTextAttributes(for: .disabled)
								normalTitleTextAttributes?[NSAttributedString.Key.foregroundColor] = UIColor.black
								highlightedTitleTextAttributes?[NSAttributedString.Key.foregroundColor] = UIColor.black
								disabledTitleTextAttributes?[NSAttributedString.Key.foregroundColor] = UIColor.black
								childVC.navigationItem.rightBarButtonItem?.setTitleTextAttributes(normalTitleTextAttributes, for: .normal)
								childVC.navigationItem.rightBarButtonItem?.setTitleTextAttributes(highlightedTitleTextAttributes, for: .highlighted)
								childVC.navigationItem.rightBarButtonItem?.setTitleTextAttributes(disabledTitleTextAttributes, for: .disabled)
								break
						}
				}
		}

This will work. It will change the done button color

UIBarButtonItem.appearance().tintColor = .green
