ios - Subclass ViewController from Storyboard

Question

I created ViewController in Storyboard and I am using

instantiateViewControllerWithIdentifier:

to load it. But I need to have this VC as base class and use 3-4 subclasses to change its properties.

How can I get an instance of my subclass with instantiateViewControllerWithIdentifier?

Answer 1

@Bhagyesh version in Swift 3:

class func instantiateFromSuperclassStoryboard() -> SubclassViewController {
    let stroryboard = UIStoryboard(name: "Main", bundle: nil)
    let controller = stroryboard.instantiateViewController(withIdentifier: "BaseViewController")
    object_setClass(controller, SubclassViewController.self)

    return controller as! SubclassViewController
}
