title: Customizing NavigationBar per XLPagerTabStrip ButtonBarPagerTabStripViewController page
body: <p>I am using XLPagerTabStrip library and using the ButtonBarPagerTabStripViewController. This is what the hierarchy looks like:
  <a href="https://i.stack.imgur.com/PJ3NV.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/PJ3NV.png" alt="enter image description here" /></a></p>
  <p>The ButtonBarPagerTabStripViewController is embedded inside a navigationController and I have two different viewControllers that the ButtonBarPagerTabStripViewController contains. The problem is that I want to change how the navigationBar looks based one either ViewController1 or ViewController2.</p>
  <p>For example, when the tab is one viewController1, I want to have a barButton &quot;+&quot;. For viewController2, I want to have a barButton of report. However, I cannot make modifications to the navigationController bar from viewController1 and viewController2.</p>
  <p>Is there a way?</p>
