Something like this should do the trick:

The UITabBarControllerDelegate has a method:

- (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController

Check this for the fifth item and return NO, then after the process of logging out is complete, set the tab to 1 programatically.

[tabBar setSelectedItem:firstController];
