Xcode 8.2模拟器显示白屏并给出SIGABRT错误

Question

I'm new to app development and I'm learning as I go. I started a new project and set the image background via image view and a png. Before preceding with anything else, I wanted to make sure that at least my background would show in the simulator.

When I run the simulator it shows a white background for a few seconds then Xcode pops up in AppDelegate with a

[4904:767382] Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Storyboard () doesn't contain a view controller with identifier 'DataViewController'' First throw call stack: `

Can anyone explain what the problem maybe?

Answer 1

Try to add the Storybaord ID ( DataViewController ) to your view controller in storybaord

a line like this may cause the crash

   let vc = self.storyboard?.instantiateViewController(withIdentifier:"DataViewController")

    self.navigationController?.pushViewController(vc!, animated: true)
