UITabBar as a UISegmentedControl???

Hi all, Is it possible to use a UITabBar as a UISegmentedControl object? I mean, instead of changing a view when the user selects an item in the uiTabBar, send an event that tells the index of the item that was pressed and therefore execute an action. Then deselect the whole UITabBar. Any sugg

That's not it then, in Snow Leopard there was a change so that message was only emitted at the end of the dealloc() method instead of at the start which allowed you to deregister your observers in dealloc() and not get this error. In Leopard and in (I think still in) iPhone OS you get the messag
