Sending an XML to WebSerivce in iPhone SDK

I want to send an XML Document(string) to WCF webservice in iOS. I开发者_JS百科 have done it in REST webservices. NO idea how to do it in WCF service. Can any one help ?

You can expose WCF services as REST endpoints if you want. How complex of a document are you sending? Do you want to use SOAP or just POST via HTTP?
