如何设置在 swift 5 中实例化后可以推送的初始 viewController

Question

使用此代码后，我无法从初始 viewController 推送

self.window = UIWindow（框架：UIScreen.main.bounds）

    let storyboard = UIStoryboard(name: "Main", bundle: nil)

    let initialViewController = storyboard.instantiateViewController(withIdentifier: Identifier)

    self.window?.rootViewController = initialViewController
    self.window?.makeKeyAndVisible()

Answer 1

您必须在 UINavigationController 中嵌入 UIViewController。 试试这个：

let storyboard = UIStoryboard(name: "Main", bundle: nil)

let initialViewController = storyboard.instantiateViewController(withIdentifier: Identifier)

let navController = UINavigationController(rootViewController: initialViewController)

self.window?.rootViewController = navController
self.window?.makeKeyAndVisible()
