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"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <soap12:Body>
    <FirmaGetir xmlns="http://tempuri.org/">
      <firID>string</firID>
    </FirmaGetir>
  </soap12:Body>
</soap12:Envelope>

返回数据

替换下面的行

 NSURL *url = [NSURL URLWithString:@"http://www.example.com/webservice1.asmx"];

通过这个。

 NSURL *url = [NSURL URLWithString:@"http://www.example.com/webservice1.asmx/ServisKontrol"];

我会帮你的。

我试图解决这个问题大约一个星期。我不再搜索它了。使用 Web 服务的最佳方式是使用带有 JSON 的 WCF 服务。我找到了一个很好的例子。请按照本教程http://www.codeproject.com/Articles/405189/How-to-access-SQL-database-from-an-iPhone-app-Via
