来自Storyboard的子类ViewController [英] Subclass ViewController from Storyboard

问题描述

我在Storyboard中创建了ViewController，我正在使用

I created ViewController in Storyboard and I am using

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。

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

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

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

推荐答案

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
}
