删除iOS项目中的storyboard
删除项目中的storyboard, (变成一个纯代码的iOS UIKit项目), 需要几步?
- 找到storyboard, 删掉它.
- 直接用ViewController.
删除storyboard
- 首先, 你得有(新建)一个storyboard项目.
- 删除storyboard. 选"Move to Trash".
- 删除plist中的storyboard name.
- 删除deploy target中的Main Interface, 本来是”main”, 把它变为空.
(截图换了一个项目名, 不要在意这些细节.)
用上自己的ViewController
在ViewController里写上自己的完美View. 比如:
import UIKit class ViewController: UIViewController { override func loadView() { view = UIView() view.backgroundColor = .systemBlue } override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. } }
设置新的rootViewController.
- 在
SceneDelegate
中设置rootViewController. (iOS 13)
class SceneDelegate: UIResponder, UIWindowSceneDelegate { var window: UIWindow? 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). guard let windowScene = (scene as? UIWindowScene) else { return } let window = UIWindow(windowScene: windowScene) window.rootViewController = ViewController() self.window = window window.makeKeyAndVisible() } ...
- tvOS没有SceneDelegate (或者你想要兼容iOS 13以前的旧版本):
import UIKit @main class AppDelegate: UIResponder, UIApplicationDelegate { var window: UIWindow? func application(_: UIApplication, didFinishLaunchingWithOptions _: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { window = UIWindow(frame: UIScreen.main.bounds) window?.rootViewController = ViewController() window?.makeKeyAndVisible() return true } ...
运行程序, 看到自己在ViewController里设置的View.
