Answer 1

You can access a instance of item (viewController,navigationController) that you assigned on a tab of UITabBarController like it –

NSArray *views = [self.tabBarController viewControllers];

Getting First Tab instance –

FirstViewController *fvc = (FirstViewController*) [views objectAtIndex:0];

You can get any tab’s viewController instance by using above code. Just change the index.
