相关疑难解决方法(0)

我正在尝试将我的应用程序转换到新的Facebook SDK 3.1(支持iOS6身份验证).

我工作得很好,所以我决定从FB网站上的授权应用程序列表中删除该应用程序,以测试iOS是否会再次请求许可.

现在我第一次调用会[FBRequest requestForMe]导致此错误:

响应:

{
  "error": {
    "message": "Error validating access token: Session does not match current stored session. This may be because the user changed the password since the time the session was created or Facebook has changed the session for security reasons.",
    "type":"OAuthException",
    "code":190,
    "error_subcode":460
  }
}

一些细节:

我正在尝试按如下方式打开会话:

                                  completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {

                                           switch (state) {
                                               case FBSessionStateOpen:
                                                   [self presentPostOptions];
                                                   break;

                                               case FBSessionStateClosed:
                                               case FBSessionStateClosedLoginFailed:
                                                   [FBSession.activeSession closeAndClearTokenInformation]; …
