ios - swift3:如何将 xib 呈现给 viewcontroller

Question

我在另一个 xib 类上添加了 xib 作为 subview ，无法从 xib 呈现给 View Controller ( Storyboard Controller )。 我试着跟随

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)

这些都不适合我

提前致谢

Answer 1

这样试试

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