1. 项目的目录结构及介绍

LaunchScreenViewController/
├── LaunchScreenViewController/
│   ├── AppDelegate.swift
│   ├── SceneDelegate.swift
│   ├── ViewController.swift
│   ├── LaunchScreen.storyboard
│   └── Assets.xcassets
├── LaunchScreenViewControllerTests/
│   └── LaunchScreenViewControllerTests.swift
└── LaunchScreenViewControllerUITests/
    └── LaunchScreenViewControllerUITests.swift

• LaunchScreenViewController/: 主项目目录，包含应用的主要代码和资源文件。

  • AppDelegate.swift: 应用的入口文件，负责应用的生命周期管理。
  • SceneDelegate.swift: 处理多场景应用的场景管理。
  • ViewController.swift: 主视图控制器，负责显示应用的主界面。
  • LaunchScreen.storyboard: 启动屏幕的界面描述文件。
  • Assets.xcassets: 资源文件夹，包含应用使用的图片和其他资源。

• LaunchScreenViewControllerTests/: 单元测试目录，包含应用的单元测试代码。

  • LaunchScreenViewControllerTests.swift: 单元测试文件。

• LaunchScreenViewControllerUITests/: UI测试目录，包含应用的UI测试代码。

  • LaunchScreenViewControllerUITests.swift: UI测试文件。

2. 项目的启动文件介绍

AppDelegate.swift

import UIKit

@main
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        return true
    }

    // Other lifecycle methods...
}

• AppDelegate.swift: 这是应用的入口文件，负责应用的启动和生命周期管理。didFinishLaunchingWithOptions 方法在应用启动后调用，可以在这里进行一些初始化操作。

SceneDelegate.swift

import UIKit

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 _ = (scene as? UIWindowScene) else { return }
    }

    // Other lifecycle methods...
}

• SceneDelegate.swift: 处理多场景应用的场景管理。scene(_:willConnectTo:options:) 方法在场景连接时调用，可以在这里进行一些初始化操作。
