我正在使用新的facebook-ios-sdk并成功将api集成到我的原生应用中。我可以使用带有ios-sdk类的弹出对话框对用户进行身份验证并正确设置权限。
对于我的应用程序的一部分，我需要在UIWebView内使用facebook连接，使用javascript和html处理webview中的数据。鉴于用户已经通过上述例程登录并进行了身份验证，我假设UIWebView将共享这些凭据，或者至少会有某种方式将凭据传递或分配给webview。
不幸的是，我发现这篇早期帖子似乎暗示这个方案不太有效（iOS - being logged-in in a webView after logging in with the SDK）。有没有其他人遇到这个和/或找到了解决方法？这似乎是一个相当简单的用例，因为我不是要尝试推出移动游猎或类似的东西 - 它都在同一个本机应用程序中。
看起来似乎必须有一些我想念的简单技巧或设置。也许以某种方式在新UIWebView中设置cookie？或类似的东西？

我可能会在此方法中获得Access令牌
func loginViewFetchedUserInfo(loginView: FBLoginView, user:FBGraphUser ) {
println(FBSession.activeSession().accessTokenData.accessToken)
}
此代码在Swift中，但该方法也适用于Obj C. 然后，您将按照Sandy和Steve
的建议在Web视图中使用访问令牌答案 2 :(得分：0)
获得FB access令牌后，您应该可以在网络视图中使用Faceboook JavaScript API。有关官方文档，请参阅http://developers.facebook.com/docs/reference/javascript/。这篇SO帖子给出了一个合理的解释：Retrieve Access Token Using Javascript API。如该帖子所述，您可以直接在AJAX电话中使用访问令牌。我不会乱用饼干 - 只需传递访问令牌。
您没有在网络视图中准确解释您想要对Facebook做什么，所以我不确定这会100％回答您的问题。我假设您知道如何将访问令牌传递到网络视图（UIWebView's stringByEvaluatingJavaScriptFromString）。
