Adding a UINavigationController to App
<p>I built up a Navigation-Based app and I want to implement that functionality in another View-Based app I'm working on. </p>

<p>I figure I can just add a subview with a UINavigationContoller and add it to the superview but I cant figure out how to set up the UINavigationController from scratch.</p>

<p>Any ideas on how to basically add a navigation-based app as a subview that can be invoked upon a button tap?</p>
