如何使用Swift从一个View Controller导航到另一个 [英] How to Navigate from one View Controller to another using Swift

问题描述

我想从一个视图控制器导航到另一个视图控制器。如何将以下Objective-C代码转换为Swift？

I'd like to navigate from one view controller to another. How can I convert the following Objective-C code into Swift?

UIViewController *viewController = [[self storyboard] instantiateViewControllerWithIdentifier:@"Identifier"];
UINavigationController *navi = [[UINavigationController alloc] initWithRootViewController:viewController];
[self.navigationController pushViewController:navi animated:YES];

推荐答案

为此创建一个swift文件（SecondViewController.swift）第二个视图控制器
并在相应的函数中键入：

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

let secondViewController = self.storyboard.instantiateViewControllerWithIdentifier("SecondViewController") as SecondViewController
self.navigationController.pushViewController(secondViewController, animated: true)
