Swift 自从iOS 13 Beta 3以来,我的应用程序只显示一个黑色窗口
以下是我的场景代理方法的代码:Swift 自从iOS 13 Beta 3以来,我的应用程序只显示一个黑色窗口,swift,ios13,Swift,Ios13,以下是我的场景代理方法的代码: func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) { // Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
// Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
// If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
// This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).
// Use a UIHostingController as window root view controller
if let windowScene = scene as? UIWindowScene {
let window = UIWindow(windowScene: windowScene)
// Override point for customization after application launch.
let context = AppDelegate.shared.persistentContainer.viewContext
context.automaticallyMergesChangesFromParent = true
window.rootViewController = UIHostingController(rootView: ContentView())
self.window = window
window.makeKeyAndVisible()
}
这是最初的默认设置。自beta 3以来,windows需要进行如下初始化:
if let windowScene = scene as? UIWindowScene {
let window = UIWindow(windowScene: windowScene)
window.rootViewController = UIHostingController(rootView: ContentView(coordinator:coord, model:store))
self.window = window
window.makeKeyAndVisible()
}

如果我没有swiftUI怎么办?@Fabiosoft那么显然你应该将视图控制器设置为rootViewController如果我没有swiftUI怎么办?@Fabiosoft那么显然你应该将视图控制器设置为rootViewController
