在Swift中实例化和呈现viewController [英] Instantiate and Present a viewController in Swift

问题描述

我开始在 Xcode 6上看一下新的 Swift ，我尝试了一些演示项目和教程。现在我被困在：

I started taking a look of the new Swift on Xcode 6, and I tried some demo projects and tutorials. Now I am stuck at:

实例化然后从特定故事板中呈现 viewController

Instantiating and then presenting a viewController from a specific storyboard

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"myStoryboardName" bundle:nil];
UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"myVCID"];
[self presentViewController:vc animated:YES completion:nil];

如何在Swift上实现这一目标？

How to achieve this on Swift?

推荐答案

这一切都是新语法的问题，功能没有改变：

It all is a matter of the new syntax, functionality hasn't changed:

// Swift 3.0

let storyboard = UIStoryboard(name: "MyStoryboardName", bundle: nil)
let controller = storyboard.instantiateViewController(withIdentifier: "someViewController")
self.present(controller, animated: true, completion: nil)

如果您遇到问题 init（编码器：），请参阅 EridB的回答。
