dialog - 验证后的第一个对话框立即失败并关闭对话框

Question

我在 iOS 5 上使用最新的 Facebook SDK。我可以使用 SSO 成功验证用户身份，然后尝试分享这样的链接:

NSString *appId = [[[NSBundle mainBundle] infoDictionary] 
                                          objectForKey:TSFacebookAppID];

NSMutableDictionary* params = 
[NSMutableDictionary dictionaryWithObjectsAndKeys:
                          appId,                @"app_id",
                          [url absoluteString], @"link
                          title,                @"caption",
                          body,                 @"description",
                          nil];

[facebook dialog:@"feed" andParams:params andDelegate:self];

第一次尝试时，对话框出现并立即关闭，调用 dialog:didFailWithError:error 委托(delegate)方法。错误是:

Error Domain=NSURLErrorDomain Code=-999 "The operation couldn’t be completed. (NSURLErrorDomain error -999.)"

但是，随后尝试共享链接工作正常。

只是给大家的更新，它终于分配给了 Facebook 的某人:https://developers.facebook.com/bugs/168127053284477 - 希望它会很快得到修复。

同时，有人在 github 上发送了一个 pull request 并修复:https://github.com/facebook/facebook-ios-sdk/pull/436

希望它可以帮助某人，因为我仍然面临同样的错误..
