如何設置在 swift 5 中實例化后可以推送的初始 viewController

Question

使用此代碼后，我無法從初始 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

您必須在 UINavigationController 中嵌入 UIViewController。 試試這個：

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()
