Can't add bar button item to navigationBar in detail viewController using Storyboard?

Question

I am adding an item to navigationBar in Main viewController, it works well. When I am adding an item to navigationBar in detail ViewController, I drag the item to ViewController, but it doesn't work, I can only add it to the top or bottom of the ViewController. And when I run the app, there is no item in the screen.

How can I add an item to navigationBar in detail ViewController by storyboard?

Answer 1

您需要为DetailsViewController添加NavigationItem，然后选择Bar Button Item，并将其拖动到刚添加的NavigationItem中。
