如何使用Swift从一个View Controller导航到另一个
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];
答
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)
Swift 2 +
Swift 2+
let mapViewControllerObj = self.storyboard?.instantiateViewControllerWithIdentifier("MapViewControllerIdentifier") as? MapViewController
self.navigationController?.pushViewController(mapViewControllerObj!, animated: true)

Swift 4
let vc = UIStoryboard.init(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "IKDetailVC") as? IKDetailVC
self.navigationController?.pushViewController(vc!, animated: true)
