OPC DA client library for Objective-C

Question

I'm developing an iPhone application with a couple of features.

Now I need to connect to an OPC DA server but I don't want to implement OPC by my self. Does an Objective-C library even exists? or are there other possible solutions for my problem (maybe C or C++ libraries?).

So I guess you want to access OPC DA Server information from an iPhone/iPad ?

OPC DA is part of the classic OPC specification and based on Microsoft COM Technology, so this might not be so easy.

A solution could be to use an OPC UA Gateway to expose your OPC DA Server over OPC UA, then use a C/C++ SDK or write your own using OPC Foundation ANSI C Stack, to get an OPC UA Client running and accessing your information.

Guys from Unified Automation (https://www.unified-automation.com/) have done some great stuff that you might want to give a look.

I am not working for this company or have any link with them, I just tried some of their products... — Camille G., May 06 '15 at 15:14
