iOS / Xcode-导航项BackBarButtonItem标题显示了以前的控制器之一

Question

i have 2 View Controllers connected by a segue within a Navigation Controller and I edited the back items titles in Interface Builder .

My problem is, that the BackBarButtonItem of the second controller shows the title of the first (and presenting) controller's BackBarButtonItem , no matter what I set for Back on the second controller's NavigationItem.

The only thing I've done is setting the leftBarButtonItem for the first Controller:

self.navigationItem.leftBarButtonItem = UIBarButtonItem(title: "Close", style: UIBarButtonItemStyle.Plain, target: self, action: "backTapped:")

Now all NavigationItems of presented Controllers show "Close". Does anyone have an idea, what's going on?

Thanks in advance

您必须在要执行后退操作的视图控制器上（例如，在前一个上）配置所需的后退按钮项目标题。
