问题
I have a tab bar setup and I want to be able to let the user change options and after the last one is selected or by pressing a button on the view, be able to automatically switch to another tab.
Simply, I have 4 tabs setup and on one, I pick an option or press a button and I want it to switch to the other tab. I have the tab bar on the main window and 4 separate views, each as a nib file.

Are you sure you want a TabBarController here and not a NavigationController? For TabBars, the answer you're looking for is to set -selectedViewController or -selectedIndex. For the specific case you list, -selectedIndex is probably your best bet.
