CGA_BaseViewController

class CGA_BaseViewController : UIViewController

This class exists only to manage the background, navbar and logo image. If we are in Dark Mode, or High-Contrast Mode, we make the background darker (and possibly monochromatic), and reduce the prominence of the logo.

  • This is a simple accessor for the app persistent preferences.
