You should use UINavigationControllers for the tabs of your UITabBarController. Then to present a new UIViewController you want to push new it onto the stack of your UINavigationController. You can do this like so:

[self.navigationController pushViewController:yourController animated:YES];

If you want the modal effect, you could do something like this:

#import <QuartzCore/QuartzCore.h>

 CATransition* transition = [CATransition animation]; transition.duration = 0.4f;
 transition.type = kCATransitionMoveIn;
 transition.subtype = kCATransitionFromTop;
 [self.navigationController.view.layer addAnimation:transition
                                                 forKey:kCATransition]
 [self.navigationController pushViewController:v animated:NO];
