Is there a way to change the default back button's color blue to my own specified color without having to set it as an image? I want to implement this using Ruby Motion.
The simplest way to do that would be inside your view controller's viewDidLoad
method, where you would chance the tint color of the navigation bar.
self.navigationController.navigationBar.tintColor = UIColor.redColor
If you want all navigation bars to have their tintColor
set to a color, you can also use UIAppearance.
UINavigationBar.appearance.tintColor = UIColor.redColor
