从已编程的按钮问题呈现UIViewController

Question

I have a UIScrollView , with a button I created in my UIViewController that presents another view controller, but when I run it, it gives me an error that it cannot find storyboard name "AddVC" though my VC is named in the storyboard id " AddVC " I do have some pictures, so please take a look at it.

here is the compiler:

here is the code: Button on top with action, with also part of a button on the bottom, ignore middle (sorry for large photo):

And the storyboard:

Please look at the images to help tell me what I am messing up, it is probably a simple fix.

Thanks - Randy

Answer 1

It looks like you have give wrong name of your storyboard. Replace the name with your actual storyboard name:

let vc = UIStoryboard(name:"Main", bundle: nil).instantiateViewController(withIdentifier:"AddVC")

Answer 2

Actually for storyboard name you have given storyboard ID. Try giving

let VC = UIStoryboard(name:<storyboard name>, bundle: nil).instantiateViewController(withIdentifier:"AddVC")
