How would you go about reading non-keyed(.csv specifically) text files in Objective-C or C with Cocoa? I know there is fscanf() but one of the requirements is having a GUI loading/saving system.
With NSFileManager you can load up the file from the disk and read in x amount of bytes at a time. Then you just load it into a data structure that allows for variable amounts of fields. Then display on the screen in a NSTableView or whatever.
