问题描述
我开始查看 Swift Programming Language，但不知何故，我无法从特定 UIStoryboard<正确键入 UIViewController 的初始化/代码>.
I started taking a look on the Swift Programming Language, and somehow I am not able to correctly type the initialization of a UIViewController from a specific UIStoryboard.
在 Objective-C 我简单地写:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"StoryboardName" bundle:nil];
UIViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:@"ViewControllerID"];
[self presentViewController:viewController animated:YES completion:nil];
谁能帮助我如何在 Swift 上实现这一目标?
Can anyone help me on how to achieve this on Swift?
推荐答案
此答案最后针对 Swift 5.4 和 iOS 14.5 SDK 进行了修订.
这完全是新语法和稍微修改的 API 的问题.UIKit 的底层功能没有改变.绝大多数 iOS SDK 框架都是如此.
It's all a matter of new syntax and slightly revised APIs. The underlying functionality of UIKit hasn't changed. This is true for a vast majority of iOS SDK frameworks.
let storyboard = UIStoryboard(name: "myStoryboardName", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "myVCID")
self.present(vc, animated: true)
确保在情节提要中的情节提要 ID"下设置 myVCID.
Make sure to set myVCID inside the storyboard, under "Storyboard ID."
