Answer 1

You can disable it (it becomes dim):

//assuming it's the right one
[[[myNavigationBar topItem]rightBarButtonItem]setEnabled: NO];

I think to hide it, you actually have to set it nil. Then recreate it when you need it.

[[myNavigationBar topItem]setRightBarButtonItem:nil animated:NO];

Answer 2

If it was just a UIButton, I'd say you can do something like this:

myButton.hidden = YES;

But if it's a UIBarButtonItem, you could try the solution here. Let us know if it works!
