Can you animate the transition between two tabs?

[sebdk]

I have a tab bar controller, and clicking a button on one tab's view switches to another tab's view. I can't figure out a way to animate the transition though. Here's the code I'm using to make the transition:

- (void)tableViewUITableView *)tableView didSelectRowAtIndexPathNSIndexPath *)indexPath {
stocksAppDelegate *delegate = [[UIApplication sharedApplication] delegate];
//[delegate.rootController selectedIndex:1];
UITabBarController *r=delegate.rootController;
r.selectedIndex=1;

I tried to change the last line to [r selectedIndex:1 animates:YES]; but it doesn't work?

Thanks for any help =)
