There are two methods in the tab bar control delegate protocol you should try: – tabBarController:shouldSelectViewController: – tabBarController:didSelectViewController:

You can hide the tab bar by calling calling tabBarController.controller.hidden = YES in the implementation of one these methods.

Note that the tab bar controller has two views; the tab bar and another view that contains the main content. I expect that you'll want to resize this content view too:

//remove the tab bars and resize the main view to fill the screen
UITabBar *tabBar = tabBarController.tabBar;
tabBar.hidden = YES;    

UIView *mainView;
for (UIView * possibleMainView in [self.view subviews])
{
    if (![possibleMainView isKindOfClass:[UITabBar class]])
    {
        mainView = possibleMainView;
        break;
    }
}

CGRect mainViewFrame = mainView.frame;
mainViewFrame.size.height += tabBar.frame.size.height;
mainViewFrame.origin.y = 0;
mainView.frame = mainViewFrame;
