Swift:
override func viewWillAppear(animated: Bool) { super.viewWillAppear(animated) var nav = self.navigationController?.navigationBar nav?.barStyle = UIBarStyle.Black nav?.tintColor = UIColor.whiteColor() nav?.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.orangeColor()] }
Objective-C:
NSDictionary *textTitleOptions = [NSDictionary dictionaryWithObjectsAndKeys:[UIColor darkGrayColor], UITextAttributeTextColor, [UIColor whiteColor], UITextAttributeTextShadowColor, nil];
[[UINavigationBar appearance] setTitleTextAttributes:textTitleOptions];
textTitleOptions = [NSDictionary dictionaryWithObjectsAndKeys:[UIColor darkGrayColor], UITextAttributeTextColor, nil];
[[UINavigationBar appearance] setTintColor:[UIColor redColor]];
[[UIToolbar appearance] setTintColor:[UIColor redColor]];
[[UIBarButtonItem appearance] setTintColor:[UIColor redColor]];

I like Alex's answer. If you want something quick to try out in a ViewController make sure you use viewWillAppear()
override func viewWillAppear(animated: Bool) { super.viewWillAppear(animated) var nav = self.navigationController?.navigationBar nav?.barStyle = UIBarStyle.Black nav?.tintColor = UIColor.white nav?.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.orange] }
