我有一个 .Net 网络服务，我将它用于移动应用程序。我在 windows phone 和 android 应用程序上使用了它，但我还没有在 iOS 上从中获取数据。例如，我的 Web 服务中有一种方法，它需要一个参数。如何从返回值中获取数据？我在互联网上找到了一个示例并对其进行了编辑，但无法获取数据。所有代码都在这里。在这种情况下，我需要一个示例代码。感谢关注。
网络服务信息：
命名空间：http ://tempuri.org url：http ://www.example.com/webservice1.asmx 方法名称：FirmaGetir 参数名称：firID（字符串）
网络服务请求：
POST /webservice1.asmx HTTP/1.1
Host: example.com
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length
<?xml version="1.0" encoding="utf-8"?>
