Add a navigation control to a single tab in xcode 4
<p>I am fairly new to programming with objective-c and xcode 4 and I am trying to make a tab bar application and add a navigation control to a specific tab. </p>

<p>I am able to add a navigation controller inside the tab bar controller, by clicking dragging the navigation controller into the tab bar controller of the MainWindow.xib window. However, by doing this and linking the class and nib to the corresponding view controller and view, respectively, this adds a new tab, which I don't want (as I want a specific/already in existence tab to also contain the nav controller).
Thanks.</p>
