Is there any function called when I press on an tabber item (at the bottom) on iPhone?
<p>Say I have a tabber item a that displays a view v1, now I push sv1 while viewing v1. If I press the tabber icon at the bottom, then I have seen that it takes me back to view v1. Is it the default behavior? Is there any function called when I press tabbar item on iPhone?</p>

<p>Thanks</p>
