I'm working on a money-handling iPhone application and would like to interact with sources using the Open Financial Exchange (OFX) standard. Information about this standard is presented here and here.
Are there any open source libraries, examples, or tutorials out there about how to interact with OFX on an iPhone or in Objective-C?
I have no experience myself, but there's a C/C++ project named LibOFX which is open source - maybe it can be tweaked in using GCC Objective-C++?
Or, if you plan on writing your own Objective-C implementation, you can look into the code of OFX4J - a Java open source implementation of the OFX specification.
I haven't tried it as yet myself but there is a objective C library called OFXKit http://code.google.com/p/ofxkit/ that looks promising and supports versions 1.x and 2.x
Some further research shows that this library does not as yet support IOS due to a dependency on a Mac OS X utility.
