Programmatically get a Storyboard ID?
You can use the restorationIdentifier, it's right above the Storyboard identifier and it's a UIViewController property.
You can use the Restoration ID:
NSString *restorationId = self.restorationIdentifier;
Just check the checkbox 'Use Storyboard ID'
The storyboard id is only meant to find and instantiate a VC from a storyboard.As written in the UIStoryboard reference:
"This identifier is not a property of the view controller object itself and is only used by the storyboard file to locate the view controller."
Why do you need it?
