Best way to set default tint for UINavigationController

I use a lot of UINavigationControllers in my app. I am using a UIColor to set the tintcolor of the navigationBar. This works as expected, but I am trying to find an easy way to set a default tintcolor for all UINavigationControllers. What is the best way to do this? Is it subclassing the UINavigationController, or is there something better?

Thanks for the hel开发者_如何学运维p.

My opinion,

...subclassing is the way to go.
