In an app I'm working on, I have a UINavigationController which has a navigation item in a xib file. I see Left Bar Button Items, Center Item Groups and Right Bar Button Items. Under Right Bar Button Items, I have a UIButton. But, in the interface of the xib file, I don't see it, even if I click on it. Further, I can't add anything to the Left Bar Button Items. In a previous version of Xcode, I had been able to put and edit the UIButton but not anymore?
What's going on?
