  <p>I applied a background image in the UINavigationBar, however, I do not know how to customize the back button. At the moment, the default back button does not suits the look &amp; feel of the customized UINavigationBar.</p>
  
  <p>Please teach me how to change the background color or image of the default back button.  Thank you.</p>
