title: Change UINavigationBar font properties?
body: <p>I have an UINavigationBar added to my UIViewController view. I want to change the fonts properties. Note that I want to change a UINavigationBar not controller. In my app where I use UINavigationController I use <code>self.navigationItem.titleView = label;</code> to display the custom label. </p>
  
  <p>How can I accomplish to have a custom title in my UINavigationBar? </p>
  
  <p>P.S I use this to set the title text <code>self.navBar.topItem.title = @"Information";</code> of my UINavigationBar. </p>
