SudzC is a tool for generating proxy code from SOAP-based web service definition files (WSDL). While it supports generating code in multiple languages, it's focus is on Objective-C.
To generate the source code, you can either visit
http://sudzc.com or download this code. Make sure your code
is accessible by your web server. Open the php/index.php page in your
browser to locally generate your code.
You might also find the
flatten-wsdl.py script useful to
prepare your WSDL files. Documentation on how to use the generated code further
can then be found in the Documentation/ directory which comes along with the
code.
