ios – Storyboard中的Subclass ViewController

我在Storyboard中创建了ViewController,我正在使用它

instantiateViewControllerWithIdentifier:

加载它.但我需要将此VC作为基类,并使用3-4个子类来更改其属性.

如何使用instantiateViewControllerWithIdentifier获取我的子类的实例？

解决方法

Swift 3中的@Bhagyesh版本：

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
}
