titleTextAttributes UIAppearance font in iOS 7

Question

I am using UIAppearance to apply fonts to UINavigationBar and UIBarButtonItem and I am having problems. I ran this code:

[[UIBarButtonItem appearanceWhenCont         


        

Answer 1

Here it is in Swift:

let font = UIFont(name: "My_Font", size: 17.0)
UINavigationBar.appearance().titleTextAttributes = [
    NSForegroundColorAttributeName: UIColor.whiteColor(),
    NSFontAttributeName: font!
]

*Note that you have to unwrap the optional UIFont.
