        if (error == nil){
            let fbloginresult : FBSDKLoginManagerLoginResult = result!
            if fbloginresult.grantedPermissions != nil {
                if(fbloginresult.grantedPermissions.contains("email")) {
                    if((FBSDKAccessToken.current()) != nil){
                        FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, picture.type(large), email"]).start(completionHandler: { (connection, result, error) -> Void in
                            if (error == nil){
                                let dict = result as! [String : AnyObject]
                                FBSDKLoginManager().logOut()
                            }
                        })
                    }
                }
            }
        }
    }
}

Facebook登录，当我从facebook界面按下继续时，它在我的iOS11.3版本上崩溃了。它在ios11.4和iOS11.03的低版本中工作得很好。

Facebook开发团队解决了这个问题。同时，我们必须对iOS11.3使用以下代码片段。如果更老的方法也能行得通，我想。

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