【问题描述】：

我正在尝试使用 Swift 4 实现 facebook 登录

Facebook 文档介绍了如何为视图控制器实现 facebook 登录按钮，但没有介绍如何使用 swift 设置 Appdelegate

谁能把这个 Objective C 代码转换成 Swift

或者放置一个 URL 链接到可以帮助我自己转换它的文档

//  AppDelegate.m
#import <FBSDKCoreKit/FBSDKCoreKit.h>

- (BOOL)application:(UIApplication *)application 
    didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

  [[FBSDKApplicationDelegate sharedInstance] application:application
    didFinishLaunchingWithOptions:launchOptions];
  // Add any custom logic here.
  return YES;
}

- (BOOL)application:(UIApplication *)application 
            openURL:(NSURL *)url 
            options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {

  BOOL handled = [[FBSDKApplicationDelegate sharedInstance] application:application
    openURL:url
    sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
    annotation:options[UIApplicationOpenURLOptionsAnnotationKey]
  ];
  // Add any custom logic here.
  return handled;
}

这不是免费的代码翻译服务。请尝试编写自己的 Swift 代码。您可以查看在 Objective-C 代码中使用哪些 API。用您尝试的 Swift 代码更新您的问题，并清楚地解释您遇到的问题。

好像你在找这个

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

和

func application(_ application: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any])  -> Bool {
      return FBSDKApplicationDelegate.sharedInstance().application(application, open: url, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String!, annotation: options[UIApplicationOpenURLOptionsKey.annotation])
}

【解决方案2】：

import UIKit
import Foundation

import FacebookCore

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?



    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

        SDKApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
        return true
    }


    @available(iOS 9.0, *)
    func application(_ application: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any]) -> Bool {
        return SDKApplicationDelegate.shared.application(application, open: url, options: options)
    }


    func applicationWillResignActive(_ application: UIApplication) {

    }

    func applicationDidEnterBackground(_ application: UIApplication) {

    }

    func applicationWillEnterForeground(_ application: UIApplication) {

    }

    func applicationDidBecomeActive(_ application: UIApplication) {

        AppEventsLogger.activate(application)
    }

    func applicationWillTerminate(_ application: UIApplication) {

    }


}
