I'm slowly learning that some people stick to C functions/types and only use NSNumber etc when they need to interop with Cocoa. Is there an equivalent for ObjC/Cocoa, or do I need to drop into C to do this? I need my code to be as accurate as possib...

This method has been replaced by dateByAddingTimeInterval:.) However, it is nowhere to be found in the docs...
I would like to create a data grid that scrolls both vertically and horizontally and has sticky row and column headers (so you can scroll the data while still viewing the row/column headers).
