xcode：在情节提要中看不到导航项

Question

I have added to my tableView with navigationController a bar button with text "Start!".

But I can not see it anymore in the storyboard.

In my build I can see it:

I think this is also the reason for this error log message:

pushViewController:animated: called on while an existing transition or presentation is occurring; the navigation stack will not be updated.

What can I do to make the bar button visible again?

Answer 1

The tableviewcontroller is covering the navbar in your storyboard. Check the properties in the storyboard and verify that your tableviewcontroller is inheriting his geometry. (setting is called inferred)
