iPhone: viewWillAppear in subviewcontroller
<p>I have one viewController in another</p>

<pre><code> [self addChildViewController:secondViewController];
</code></pre>

<p>So when viewWillAppear called for firstViewController, its will call same method for secondviewController too.</p>

<p>How to prevent that ? I want viewWillAppear called only for parent.</p>
