解析Facebook登录失败，错误代码为251 [英] Parse Facebook login fails with error code 251

问题描述

我正在尝试使用Parse Facebook&我的应用程序中有Twitter登录，但问题是我无法使Facebook登录正常工作.

I'm trying to use Parse Facebook & Twitter login in my app but the problem is I can't get the Facebook login to work.

我收到以下错误消息:

    Error Domain=Parse Code=251 "The operation couldn’t be completed. (Parse error 251.)" UserInfo=0xa0329c0 {code=251, error=The supplied Facebook session token is expired or invalid.

我还下载了Parse教程"IntegratingFacebookTutorial"，并且仍然存在相同的错误.

I also downloaded the Parse tutorial "IntegratingFacebookTutorial" and still the same error.

((我将捆绑软件添加到了Facebook应用中，并根据需要在xcode上更新了应用ID.

(I added the bundle to the facebook app and updated the application id on xcode as required.

当我尝试使用PFLogInViewController时，在我自己的项目中也会发生同样的情况，相同的设置+我正在调用[PFFacebookUtils initializeFacebook]；在我的didFinishLaunchingWithOptions中.

The same happens in my own project when trying to use PFLogInViewController, same setup + I'm calling [PFFacebookUtils initializeFacebook]; in my didFinishLaunchingWithOptions.

我发现了有关此问题的几份报告，但到目前为止零解决方案.

I found several reports about this issue but zero solutions so far.
