我的应用程序不使用 Storyboard。所有 View 均以编程方式创建。
过去,我已经删除了我的 Main.storyboard
,从我的 Info.plist
中删除了引用并设置了我的 UIWindow
和 rootViewController
如下:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
let window = UIWindow(frame: UIScreen.main.bounds)
window.rootViewController = UIViewController()
window.makeKeyAndVisible()
self.window = window
return true
}
但是,当尝试在 iOS 13 中运行我的应用程序时,我遇到了崩溃 -
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Could not find a storyboard named 'Main' in bundle NSBundle </Users/Dev/Library/Developer/CoreSimulator/Devices/8A4474B1-FCA3-4720-8F34-A6975A03EE19/data/Containers/Bundle/Application/258FA246-A283-4FE6-A075-58BD32424427/Home.app> (loaded)'
***
iOS 12 仍按预期运行。我应该如何以编程方式设置我的 View 以支持 iOS 12 和 13?
最佳答案
您还需要添加更新 SceneDelegate.swift
。
更新 func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions)
并添加
guard let windowScene = (scene as? UIWindowScene) else { return }
let window = UIWindow(windowScene: windowScene)
let viewController = ViewController()
window.rootViewController = viewController
window.makeKeyAndVisible()
self.window = window
关于iOS 12/13 程序化 View 创建,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/58296932/
