How to Navigate from one View Controller to another using Swift(如何使用 Swift 从一个视图控制器导航到另一个视图控制器)

问题描述

我想从一个视图控制器导航到另一个.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

为第二个视图控制器创建一个swift文件(SecondViewController.swift)并在适当的函数中输入:

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)

self.navigationController?.pushViewController(mapViewControllerObj!, animated: true)
