如何使用Swift从一个View Controller导航到另一个

swift

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？

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

为第二个视图控制器创建一个swift文件（SecondViewController.swift），并在适当的函数中键入以下内容：

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

迅捷2+

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

let vc = UIStoryboard.init(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "IKDetailVC") as? IKDetailVC
self.navigationController?.pushViewController(vc!, animated: true)
