在界面生成器中添加UIBarButtonItem到导航的UIViewController？

Question

I have a UINavigationController in Interface Builder in a storyboard. I've added two UIBarButtonItems to the first UIViewController . They display just fine. How can I add them to the second UIViewController which is navigatated to? On that view controller, I only see the Back button.

When I try dragging a UIBarButtonItem to the top of the second view controller, the button ends up at the bottom of the scene for some reason. It is not displayed when running the app.

Edit: I should have mentioned that I know how to do this in code, but not in Interface Builder.

Answer 1

To add further informations about my comments concerning navigation item :

Here is a simple project with a UIViewController embedded in a UINavigationController . A second UIViewController can be pushed via the Next button. If you select the next button, you can see in the hierarchy that this button is embedded within the group Right Bar Buttons Items , which is embedded within the First object. In fact, First is a UINavigationItem automatically added to your view controller when it was embedded in the navigation controller.

But the second view controller (the pushed one) doesn't have this navigation item since it isn't directly embedded within a navigation controller. Simply drag and drop it from the Object Library to your view controller.

@Slack, As i said earlier just drag and drop 2 "bar button item" in your navigation bar.
