Facebook SDK iOS错误2 [英] Facebook SDK iOS error 2

问题描述

  [FBSession openActiveSessionWithReadPermissions：permissions 
 allowLoginUI： YES 
 completionHandler：^（FBSession * session，FBSessionState state，NSError * error）{
 [self sessionStateChanged：session state：state error：error]; 
}] 
  

我遇到的问题是在iOS 6.x中的设备在设置应用程序中有一个没有登录的facebook帐户。它给出的错误是看似一个大小适合的错误2 。这是唯一失败的情况，我不明白为什么。有一个解决方案让我在一个帐户被链接时登录？

解决方案

检查你的权限数组不包含 offline_access 权限。此权限现在是已弃用，并且已知导致登录失败。我以前搜索堆栈溢出，并发现此答案。您还需要进入设置 - > Facebook并将允许的应用程序的权限切换到开启。

I'm trying to log into facebook with their API using

[FBSession openActiveSessionWithReadPermissions:permissions
                                   allowLoginUI:YES
                              completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {
                                                     [self sessionStateChanged:session state:state error:error];
                                                 }]

The problem I'm having is in iOS 6.x when the device has a facebook account linked in the settings app it fails to log in. The error it gives is the seemingly one-size-fits-all error 2. This is the only case where it fails and I can't understand why. What is a solution to let me log in while an account is linked?

解决方案

check that your permissions array does not contain the offline_access permission. this permission is now deprecated and has been known to cause login to fail. i previously searched stack overflow and found this answer. you'll also need to go into Settings -> Facebook and switch the permission on the Allowed Apps to On.
