Avoid hard coding storyboard IDs in 2 places

When I want to set an ID for a View Controller I go into the storyboard file, select the ViewController, then on the Identity inspector I type in the Storyboard ID as something like "theVCID":

enter image description here

When I want to use that View Controller in code I do something like:

UIViewController *myVC = [myStoryboard instantiateViewControllerWithIdentifier:@"theVCID"];

Is there a way I can just hardcode this ID string in one location instead of hard coding it inside storyboard and when I use it in code?

If I could get a variable in the storyboard XML, I could just get the hardcoded string variable inside the XML source, but I don't know how/where to set up a variable so that the storyboard XML can access it.

Unfortunately you are forced to duplicate the declaration.

I wouldn't recommend parsing the XML as you will be basing that on the assumption of an implementation detail. Technically, storyboards could change their data type to anything in the future and this would break your implementation.

The safest way to do this is to keep your storyboard identifiers in a single class (say StoryBoardCoordinationController) and simply reference the storyboard objects through this single interface. Hopefully you should never be in the situation where these values are changing often, and if they are you should definitely seek to do something about it:)
