(lldb) po self.storyboard nil

Question

How/when can a UIViewController return self.storyboard nil.

I am trying to instantiate a ViewController with:

self.storyboard!.instantiateViewControllerWithIdentifier

But self.storyboard is nil?
Note: the plist is set to the right storyboard.

Answer 1

Per the Apple documentation , UIViewController 's storyboard property represents the storyboard from which the view controller originated. It returns an optional UIStoryboard instance which is nil if the view controller was not instantiated from a storyboard.

Answer 2

尝试这个 ：

let localStoryboard = UIStoryboard(name: "Main", bundle: nil)
