(Objective-C) HTTP SOAP 1.2 Request and Response using POST

Demonstrates a working SOAP 1.2 request and response using POST with a live server. You may try running this example with the URLs and data provided. See http://wsf.cdyne.com/WeatherWS/Weather.asmx?op=GetCityWeatherByZIP for details.

Note: This example is correct in theory, but no longer works for live testing because the SOAP service provider (cdyne.com) has made changes or discontinued the free service.

Note: This example requires Chilkat v11.0.0 or greater.
