Issue related to state maintenance
<p>I have 10 views with <code>UINavigationController</code> in hierarchy. Now when I want to go back from 10 to 9, and so on with back button, which method  should I use?</p>

<ol>
<li><code>popviewController</code></li>
<li><code>popToViewController</code></li>
</ol>

<p>I have set a fixed value for all views. At application launch, I get that value. For that value I initialize <code>rootviewController</code> with use of <code>UINavigationController</code>. And my <code>rootviewController</code> is nothing but the first view and after that on next line, I'm pushing a particular view.</p>
