iphone - Select no tabs in a UITabBar

I'm trying to select no tabs at all in my application. At first the first tab is selected, but I'd like to deselect it so no tabs at all would be selected.

Don't ask me why, it's just that way the client wants it! hehe

Thanks for your help!

PS: I already tried:

// rootController = UITabBarController    
rootController.tabBar.selectedItem = 0;
rootController.tabBar.selectedItem = nil;
[rootController setSelectedIndex:[rootController.items objectAtIndex:0]];
[rootController setSelectedIndex:nil];
[rootController setSelectedIndex:0];
// That one works : (but I can't select 0 or -1 for instance)
[rootController setSelectedIndex:2];

Any ideas? Thanks again!

You can deselect all tab bar items if you are using UITabBar instance without UITabBarController one.

In such case below code works well.

[tabBar setSelectedItem:nil];

If UITabBar is a part of UITabBarController then application will crash with exception:

'Directly modifying a tab bar managed by a tab bar controller is not allowed.'

In other words if you would like to get this worked you need to manage tabbar's routines manually without controller.
