如何在iOS App中完全注销Facebook SDK Auth [英] How to completely Logout of Facebook SDK Auth in iOS App

问题描述

使用FBSDKCoreKit 4.22.1

using FBSDKCoreKit 4.22.1

我公开安装了一个应用程序，在白天为多个用户提供服务。一个人可以走到iPad并使用他们的Facebook帐户登录：

I have an app installed publicly, servicing multiple users during the day. A person can walk up to the iPad and login with their Facebook account:

成功登录后，可以完成他们的工作并使用应用程序而不是他们将在稍后注销：

After successful login, than can do their work and use the app and than they will logout some time later:

Logout发生成功。然后下一个用户开始使用公共iPad并点击Facebook登录按钮，但他们会看到：

The Logout happens successfully. Then the next user comes up to use the public iPad and clicks the Facebook Login button, yet they will see:

FBSDKLoginManager或其他Facebook SDK Libs记住了之前用户Facebook登录的一些元素。

The FBSDKLoginManager or other Facebook SDK Libs has remembered some elements of the previous user's Facebook login.

我想彻底清除有关以前用户的Facebook凭据的任何信息

成功注销后，调用此 FBSDKLoginButtonDelegate 方法，我已尝试以下方法完全删除Facebook帐户信息没有成功：

After successful Logout, this FBSDKLoginButtonDelegate method is called and I have tried the following to completely remove the Facebook account info with no success:

func loginButtonDidLogOut(_ loginButton: FBSDKLoginButton!) {
    print("\(#function) in \(#file.components(separatedBy: "/").last ?? "")")
    print("Todo, must completely remove Facebook Auth token info for current user logging out")
    FBSDKAccessToken.setCurrent(nil)
    FBSDKLoginManager().logOut()
    FBSDKProfile.setCurrent(nil)
}

所以使用FBSDKCoreKit 4.22.1 Safari浏览器用于打开Facebook身份验证重定向URL，Javascript使用本地存储：

So with FBSDKCoreKit 4.22.1 Safari browser is used to open the Facebook authentication redirect URL and that Javascript uses local storage:

有趣的是，阻止所有Cookie，Apple暗示也将阻止网站数据（localStorage），不阻止本地存储和Facebook仍然创建网站数据存储：

Interestingly, Blocking all Cookies, which Apple implies will also block Website Data (localStorage), does NOT block local storage and Facebook and still create Web Site data stores:

Apple说这里：

更改哪个cookie接受s和网站数据：选择Cookies和网站数据选项：

"Change which cookies and website data are accepted: Select a "Cookies and website data" option:"

• 始终阻止：Safari不允许任何网站，第三方或
  广告客户在您的Mac上存储Cookie和其他数据。这可能是
  阻止某些网站正常工作。

这就是我希望本地存储也被阻止的地方作为cookie但Facebook仍然可以创建本地存储条目

And that is where I expect Local Storage to be blocked as well as cookies but Facebook can still create local storage entries
