make invisible a UIBarButtonItem

Question

I can make an invisible UIBarButtonItem on UIToolbar, inserted with XCode / Storyboard? I have found a property to disable it: enabled = NO, but is not made it invisible

Answer 1

    NSMutableArray *items = [YourToolBar.items mutableCopy];
    [items removeObject:BarButton];
    YourToolBar.items = items;
    [items release];
