I'd like to be able to change the highlighted state image on an UITabBarItem when it is selected? Is it possible to subclass and access this? or do I need to roll my own navigation code?
-> start edit I didn't articulate what I was looking for earlier. I am looking for the semi-transparent white overlay reference that the device adds to the selected state/image of the UITabBar. See image! http://solomon71.com/images/UITabBarItem.png
There is no documented or supported way to set your own highlighted image. Having said that, in 2.2 you could do it by subclassing UITabBarItem and implementing -[UIImage *)selectedImage.
Strictly speaking you are not calling private API, since selectedImage is not a reserved method name (and is actually a fairly reasonable name for someone to use themselves). Having said that, I am sure this is not intended and it could break at any time in a future release. It wouldn't shock me if this was already broken in 3.x (I never shipped anything that did this, just experimented with it for a client).
