Hiding UInavigationItem's bar button
<p>I have added a BarButton item to the left of the nav.bar through Interface Builder and in the code i want this only to show in my table view's edit mode. But i didn't find any Hidden property to set the leftBarButtonItem (like: self.navigationItem.leftBarButtonItem.hidden = YES). I can only set 'enabled' property. Anybody know how to control the hide and show property of the leftBarButtonItem, please help.</p>
