【问题描述】：

如何在 ios 14(SwiftUI) 小部件扩展中初始化 Facebook SDK？我需要在哪里调用下面的方法？

ApplicationDelegate.shared.application( application, didFinishLaunchingWithOptions: launchOptions)  

我的最终目标是从我的小部件中调用 GraphRequest。而根据documentation，调用graph request需要先初始化Facebook SDK。

提前致谢！

【参考方案1】：

HackingWithSwift 有一个解决方案 https://www.hackingwithswift.com/quick-start/swiftui/how-to-add-an-appdelegate-to-a-swiftui-app

它在主视图中使用 AppDelegate

【参考方案2】：

只是一个小提示： 如果您正在从头开始编写应用程序并认为您将需要 Appdelegate 逻辑，您可以在开始时选择：

你在哪里得到：

@main
class AppDelegate: UIResponder, UIApplicationDelegate 


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

    // MARK: UISceneSession Lifecycle

    func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration 
        // Called when a new scene session is being created.
        // Use this method to select a configuration to create the new scene with.
        return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
    

    func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) 
        // Called when the user discards a scene session.
        // If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
        // Use this method to release any resources that were specific to the discarded scenes, as they will not return.
