How do you code two different tabbars in one iPhone App?
<p>My app requires one set of tabs on the initial view, the last tab item is reserved for an in-app purchase once the user selects. However, once the user makes the in-app purchase I would like a new set of tabs to appear. I would like for the user to be able to switch back and forward between the free part of the app and the in-app purchase part of the app with different tab bars. For example: </p>

<p><strong>"TabBar1"</strong> to have <strong>"TabItem 1"</strong>, <strong>"TabItem 2"</strong>, <strong>"TabItem 3"</strong>, and <strong>"TabItem 4"</strong> for my Free App, when user selects <strong>"TabItem 4"</strong> ...a welcome or in-app purchase screen will appear. If user makes the in-app purchase, <strong>"TabBar2"</strong> appears with <strong>"TabItem 1"</strong>, <strong>"TabItem 5"</strong>, <strong>"TabItem 6"</strong>, and <strong>"TabItem4"</strong>. <strong>"TabItem1"</strong> will bring you back to Free part of app and <strong>"TabBar1"</strong> when selected again. Hope I didnt confuse...How do you accomplish this? Thanks for the help. </p>

<p>I forgot to add that this Tabbar is to be combined with a Navigation controller as well.</p>
