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 controllerand in the appropriate function type this:

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

let mapViewControllerObj = self.storyboard?.instantiateViewControllerWithIdentifier("MapViewControllerIdentifier") as? MapViewController
self.navigationController?.pushViewController(mapViewControllerObj!, animated: true)
