iOS开发删除storyboard步骤详解

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.

  • 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.
