For now KxSMB supports a limited set of SMB operations. It mostly was designed for browsing local net and retrieving files.

First you need download, configure and build samba. For this open console and type in

cd kxsmb	
rake

1. Drop files from kxsmb/libs folder in your project.
2. Add libs: libz.dylib, libresolv.dylib and liconv.dylib.

Fetching a folder content:

NSArray *items = [[KxSMBProvider sharedSmbProvider] fetchAtPath: @"smb://server/share/"];

Reading a file:

KxSMBItemFile *file = [[KxSMBProvider sharedSmbProvider] fetchAtPath: @"smb://server/share/file"];
NSData *data = [file readDataToEndOfFile];

Look at kxSMBSample demo project as example of using.

at least iOS 5.0 and Xcode 4.5.0
