在iPhone上使用Objective-C使用WCF Web服务

问题描述

我很难在我的iPhone应用程序中使用非常简单的（Hello World）WCF Web服务。根据我的阅读，您必须手动创建请求消息，然后将其发送到Web服务URL。

I am having a hard time consuming a very simple (Hello World) WCF web service in my iPhone app. From what I have read, you must manually create the request message then send it to the web service URL.

我能够在.asmx网络服务上完成此任务，但不能使用WCF服务。

I was able to accomplish this on a .asmx web service, but not with a WCF service.

我如何知道请求SOAP消息的正确格式？

How do I know the correct format of the request SOAP message?

我尝试访问的Web服务格式为：
（在VM中本地运行） ）

The web service I am trying to hit has a format of:http://xxx.xxx.xxx.xxx:PORT/IService1/ (running locally in a VM)

我为缺乏信息道歉，我很遗憾。

I apologize for the lack of information, I am pretty lost.

任何和所有帮助都很多赞赏。

Any and all help is much appreciated.
