ios - 实现 Facebook 登录 IOS

Question

我正在尝试按照 facebook 开发者网站的说明来实现他们的登录。第 5 步告诉我向我的 AppDelegate 类添加一些代码，特别是 AppDelegate.m(我没有，我只有 AppDelegate.swift)。

这是我应该添加的代码:

//  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;
}

如果我尝试将它放入 AppDelegate.swift 文件中，我会遇到各种错误，而且我找不到任何好的文档来正确执行此操作。我该如何解决这个问题？

objective-c 中的代码，你应该使用 swift

import FBSDKCoreKit

import FBSDKLoginKit

  func application(_ application: UIApplication,didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
       FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
       return true
  }

  func application(_ app: UIApplication,open url: URL,options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool
  {

    if #available(iOS 9.0, *) {
        let sourceApplication: String? = options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String
        return FBSDKApplicationDelegate.sharedInstance().application(app, open: url,sourceApplication: sourceApplication, annotation: nil)           

    } 
     return true
  }

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