以前处理 FBSDKLoginKit，我必须为我的 appDelegate.swift 使用某些代码才能使 facebook 登录工作，如下所示：
import FBSDKLoginKit
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
let fbLaunch = FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
return fbLaunch
}
func applicationWillResignActive(_ application: UIApplication) {
FBSDKAppEvents.activateApp()
}
func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(application, open: url, sourceApplication: sourceApplication, annotation: annotation)
}
现在我切换到 FacebookLogin，上面的代码是什么？
