swift3：如何将xib呈现给viewcontroller

Question

我已将xib添加到另一个xib类作为子视图，并且无法从xib呈现给视图控制器（Story Board控制器）。 我试过跟着

1

let screen:Screen32ViewController = Screen32ViewController()
self.view.window?.rootViewController?.present(screen!, animated: true,  completion: nil)

2

let screen = self.storyboard?.instantiateViewController(withIdentifier: "Screen32ViewController") as? Screen32ViewController
self.present(screen!, animated: true,  completion: nil)

3

let screen:Screen32ViewController = Screen32ViewController()
self.present(screen!, animated: true,  completion: nil)

这不适用于我

提前致谢

Answer 1

试试这个

let screen = UIStoryboard(name: "storyboard name", bundle: nil).instantiateViewController(withIdentifier: "Screen32ViewController") as?   Screen32ViewController
self.present(screen!, animated: true,  completion: nil)
