ios - 访问 Cocoa 框架 Storyboard

Question

我有带有两个 Controller 类和 Storyboard的 Swift Cocoa Touch 框架。当我尝试 instantiateViewController 从一个类到另一个类时，它不起作用，它显示 Storyboard不可见。

我可以使用以下方法从基础项目启动test.storyboard:

 if let urlString = Bundle.main.path(forResource: "testProject", ofType: "framework", inDirectory: "Frameworks") {
            let bundle = (Bundle(url: NSURL(fileURLWithPath: urlString) as URL))
            let sb = UIStoryboard(name: "test", bundle: bundle)
            let vc = sb.instantiateViewController(withIdentifier: "TestViewcontroller")
            self.show(vc, sender: nil)
 }

我想在单击第一个 View Controller 时实例化第二个 View Controller 。现在我正在使用此代码块进行启动，但它不起作用。

 if let urlString =  Bundle.main.path(forResource: "testProject", ofType: "framework", inDirectory: "Frameworks") {
            let bundle = (Bundle(url: NSURL(fileURLWithPath: urlString) as URL))
            let secondvc = UIStoryboard(name: "test", bundle: bundle).instantiateViewController(withIdentifier: "secondViewc") as! secondcontroller

            self.show(secondvc, sender: nil)
 }

Answer 1

最后，我找到了解决问题的办法。

@IBAction func back(_ sender: AnyObject) {
     let frameworkBundle = Bundle(for: Maincontroller.self)
     let secondvc = UIStoryboard(name: "test", bundle: frameworkBundle).instantiateViewController(withIdentifier: "secondViewc") as! secondcontroller
     self.present(secondvc, animated: true, completion: nil)
}

在 testProject -> Maincontroller.swift 中，必须添加上面的代码块。
