Question

我使用WSDL2Objc生成的代码从我的应用程序成功调用WS。我将我的应用程序发送给同事用于测试目的，并且他们报告我在尝试连接到WS时App崩溃了。事实上iPad背后是HTTP身份验证代理。

根据我的理解，身份验证代理会将连接重定向到HTTP页面，该页面会显示“请提供凭据”等消息

我必须避免崩溃，只是显示错误，但我无法理解崩溃发生的位置。我已经将崩溃日志和崩溃的线程标记为粘贴日志。

感谢任何帮助。

Answer 1

HTTP会话的管理存在细微错误。我在这个博客中喜欢暗示 EXC_BREAKPOINT strange error 本质上问题出在NSURLConnection的didReceiveAuthenticationChallenge中。出于某些原因，仅针对某种服务，didReceiveAuthenticationChallenge将NULL凭据传递给连接，以便博客建议我尝试保留这些凭据字符串并且EXC_BREAKPOINT消失。
