swift - 如何在Scene Delegate iOS 13中设置rootViewController

在UIKit iOS 13中进行更改之前，如何在SceneDelegate中设置rootViewController？

class SceneDelegate: UIResponder, UIWindowSceneDelegate {

    var window: UIWindow?


    @available(iOS 13.0, *)
    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        guard let _ = (scene as? UIWindowScene) else { return }

    }

最佳答案

仅供引用，因为SwiftUI不使用 Storyboard ，如果您仅创建一个新的SwiftUI项目，它将为您提供代码；您需要做的就是用所需的根VC替换UIHostingViewController，如下所示:

class SceneDelegate: UIResponder, UIWindowSceneDelegate {

  var window: UIWindow?

  func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {

    if let windowScene = scene as? UIWindowScene {
        let window = UIWindow(windowScene: windowScene)
        window.rootViewController = MyRootViewController()
        self.window = window
        window.makeKeyAndVisible()
    }
  }
