UIWebView + Sharepoint + NTLM身份validation – 我得到stream是在打开之前发送一个事件

我一直在一个有一个简单的UIWebView的应用程序，它显示一个Sharepoint网站。 我原本以为NTLMauthentication是一个问题，但事实certificate这是非常简单的。 然而，自iOS8以来，我的应用程序一直在垃圾邮件“stream正在打开之前发送一个事件”一遍又一遍在我的日志中，该网页真的永远不能加载。

我原本以为这是我正在做的事情，所以我创build了一个小应用程序（下）以消除我的其他应用程序可能有的任何古怪，但不幸的是，我得到同样的问题。 我想我的主要问题是我不知道该从哪里开始寻找答案。 互联网有一些提到这个，但没有像[webView dontDoThat]清晰的决议。 ：d

我正在玩手动添加连接到运行循环，你会在代码中看到这个。 我已经尝试了各种方式，我知道如何创build连接，但这是最近的尝试。

我开始处理SSL挑战，因为我的证书对域无效，于是我得到NTLM挑战，并发送硬编码的用户名，并通过testing。 它部分加载网站，但最终放弃加载所有的资源，我认为是这个错误。 理论的欢迎。

免责声明：零件和零件是从其他人复制的，所以我不声称已经手动input每一行。 感谢你们所有的代码，我把这个例子。

任何帮助感激！ – 格雷格框架
