How to access SOAP services from iPhone

Question

I m planning to develop an app for the iPhone and that app would have to access a couple of SOAP services  While doing some basic checking in the iPhone SDK I was not able to find any support for accessing SOAP services  a bit of Googling lead to the conclusion that there is no support for SOAP in the iPhone SDK    So if I do want to build that app I ll need to come up with a approach to access SOAP services from the iPhone  What would be the best approach  Any best practices  Did someone already write a library using the functionality that is present in the iPhone SDK to access SOAP services    Since the service I need to access is exposed by another party and they only expose it as SOAP  it s unfortunately not an option to switch to another type of interface  e g  REST based API    Gero

I ve historically rolled my own access at a low level  XML generation and parsing  to deal with the occasional need to do SOAP style requests from Objective-C  That said  there s a library available called SOAPClient  soapclient  that is open source  BSD licensed  and available on Google Code  mac-soapclient  that might be of interest   I won t attest to it s abilities or effectiveness  as I ve never used it or had to work with it s API s  but it is available and might provide a quick solution for you depending on your needs   Apple had  at one time  a very broken utility called WS-MakeStubs  I don t think it s available on the iPhone  but you might also be interested in an open-source library intended to replace that - code generate out Objective-C for interacting with a SOAP client  Again  I haven t used it - but I ve marked it down in my notes  wsdl2objc

My solution was to have a proxy server accept REST  issue the SOAP request  and return result  using PHP     Time to implement  15-30 minutes   Not most elegant  but solid

One word  Don t   OK obviously that isn t a real answer  But still SOAP should be avoided at all costs   -  Is it possible to add a proxy server between the iPhone and the web service  Perhaps something that converts REST into SOAP for you   You could try CSOAP  a SOAP library that depends on libxml2  which is included in the iPhone SDK    I ve written my own SOAP framework for OSX  However it is not actively maintained and will require some time to port to the iPhone  you ll need to replace NSXML with TouchXML for a start

Here is a swift 4 sample code which execute API calling using SOAP service format          func callSOAPWSToGetData              let strSOAPMessage                 lt  xml version   1 0   encoding   utf-8    gt                       lt soap Envelope xmlns xsi   http   www w3 org 2001 XMLSchema-instance   xmlns xsd   http   www w3 org 2001 XMLSchema   xmlns soap   http   schemas xmlsoap org soap envelope    gt                       lt soap Body gt                       lt CelsiusToFahrenheit xmlns   http   www yourapi com webservices    gt                       lt Celsius gt 50 lt  Celsius gt                       lt  CelsiusToFahrenheit gt                       lt  soap Body gt               lt  soap Envelope gt            guard let url   URL init string   http   www example org   else               return                   var request   URLRequest init url  url          let length    strSOAPMessage as NSString  length         request addValue  application soap xml  charset utf-8   forHTTPHeaderField   Content-Type           request addValue  http   www yourapi com webservices CelsiusToFahrenheit   forHTTPHeaderField   SOAPAction           request addValue String length   forHTTPHeaderField   Content-Length           request httpMethod    POST          request httpBody   strSOAPMessage data using   utf8           let config   URLSessionConfiguration default         let session   URLSession configuration  config          let task   session dataTask with  request     data  response  error  in             guard let responseData   data else                   print  Error  did not receive data                   return                           guard error    nil else                   print  error calling GET on  todos 1                   print error                        return                           print responseData              let strData   String init data  responseData  encoding   utf8              print strData                          task resume

Have a look at gsoap that includes two iOS examples in the download package under ios plugin  The tool converts WSDL to code for SOAP and XML REST
