UINavigationBar.itents accessor does not return the current UINavigationItem

Question

In my function, UINavigationBar: didPopItem:the navigation bar _itemStackhas n elements in it displayed in the debugger, but the accesser function .itemsreturns an array with n-1 elements in it, the absence of the current navigation element that I want to check. backItemreturns element n-2 instead of n-1, etc. The element didPopItemis an "n + 1" element, so that doesn't help either.

How do I access the current UINavigationItem?

I am using the iPhone 3.0 SDK.

    [ self performSelector:@selector(XXX) withObject:nBar afterDelay:0 ];
}
