Getting Data From .net Web Service on iOS - iphone

Question

I have one .Net web service and I use it for mobile apps. I used it on windows phone and android apps but I didn't get data from it on iOS yet. For example, there is one method in my web service and it takes one parameter. How can I get data from returning value ? I found one example on internet and I edited it but I can't get data. All of code is here. In this case I need a sample code. Thanks for attention.
web service's information:
namespace : http://tempuri.org
url : http://www.example.com/webservice1.asmx
method name : FirmaGetir
parameter name: firID (string)
Web service request:
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>
Returning data:

Content-Type: application/soap+xml; charset=utf-8
Content-Length: length

Answer 1

Replace the line below
NSURL *url = [NSURL URLWithString:#"http://www.example.com/webservice1.asmx"];
by this one.
NSURL *url = [NSURL URLWithString:#"http://www.example.com/webservice1.asmx/ServisKontrol"];
It will help.

Answer 3

I was trying solve this issue about one week. I don't search anymore about it. The best way for consuming web service is using WCF services with JSON. I found an excellent example about of it. Please follow this tutorial http://www.codeproject.com/Articles/405189/How-to-access-SQL-database-from-an-iPhone-app-Via

Answer 4

Change http://tempuri.org/FirmaGetir with http://tempuri.org/ServisKontrol in SOAPAction.
