如何在swift中切换视图控制器？ [英] How to switch view controllers in swift?

问题描述

我正在尝试使用代码从一个UIViewController切换到另一个。现在我有，

I'm trying to switch from one UIViewController to another using code. Right now I have,

self.presentViewController(ResultViewController(), animated: true, completion: nil)

所有这一切都是把我带到黑屏而不是ResultViewController。有什么建议么？

All this is doing is taking me to a black screen instead of the ResultViewController. Any suggestions?

推荐答案

使用Storyboard。为第二个视图控制器
创建一个swift文件（SecondViewController.swift），并在相应的函数中输入：

With Storyboard. Create a swift file (SecondViewController.swift) for the second view controller and in the appropriate function type this:

let secondViewController = self.storyboard?.instantiateViewController(withIdentifier: "secondViewController") as! secondViewController

self.navigationController.pushViewController(secondViewController, animated: true)

没有故事板

let secondViewController = ViewController(nibNameOrNil: NibName, bundleOrNil: nil)
self.presentViewController(secondViewController, animated: true, completion: nil)
