RootViewController - iPhone
<p>I am new to iPhone programming and trying to grasp the concept of RootViewController. </p>

<p><strong>Scenario:</strong> </p>

<p>I have 3 views</p>

<ol>
<li>RootViewController - Parent View</li>
<li>SportsViewController - Sub View 1</li>
<li>CricketViewController - Sub View 2</li>
</ol>

<p>Both the subview have to be in FullScreenMode, so tab-bar or navigation bar cannot be used.</p>

<p>At first, Sub View 1 is loaded which is having some content and a DONE button on it. 
Once user press DONE button then Sub View 1 has to be unloaded and RootViewController should load the Sub View 2.</p>

<p><strong>Query</strong></p>

<p>I have successfully displayed SubView 1 and when user taps on DONE then I can unload it. But I did n't get how should I notify the RootViewController from Sub View 1 that Sub View 1 has unloaded and now it should load the Sub View 2?</p>

<p>Thanks in Advance</p>
