I'm new to iOS, have been developing in Delphi for many years.
I don't know FPC well and i find it very hard to figure out which classes are available on iOS.
is there any FireMonkey classes for calling web services and parsing xml?
回答1:
Yes you can call a webservice :)
No it is not simple :(
You need to access the iOS framework directly...
The following code fragments will help...
First a pascal example of how to send/receive data via TCP

Secondly, you will need to wrap the call using the relevant headers. See...

It is a fair bit of work, but it can be done. Good luck!

You can also try to use RealThinClient (RTC) SDK to allow your Delphi XE2 FireMonkey iOS client to connect to a RTC SDK server. Not SOAP, but I've managed to send data back and forth between the two layers (just in case you do not have to use SOAP, but are merely looking for some way to connect an iOS client to a server)...
