ios - 从xib文件加载ViewController

我有一个MyViewController.swift和MyViewController.xib介绍MyViewController的布局。

我尝试了其他方法来加载此 View Controller ，包括:

//1
let myVC = UINib(nibName: "MyViewController", bundle:
       nil).instantiateWithOwner(nil, options: nil)[0] as? MyViewController

//2
let myVC = NSBundle.mainBundle().loadNibNamed("MyViewController", owner: self, options: nil)[0] as? MyViewController

//3
let myVC = MyViewController(nibName: "MyViewController", bundle: nil)

第三个是唯一成功的初始化，但是前两个正在导致错误:



这些加载方法有什么问题？

最佳答案

swift 3

let myViewController = MyViewController(nibName: "MyViewController", bundle: nil)
self.present(myViewController, animated: true, completion: nil)

或插入导航 Controller

self.navigationController!.pushViewController(MyViewController(nibName: "MyViewController", bundle: nil), animated: true)
