What Cocoa/Core Foundation helper functions do you wish you knew about 2 years ago?

Question

I just discovered the NSRect helper functions in NSGeometry.h (i.e. NSMidX, NSMaxX, etc...)

These would have made some repetitive coding much easier. I knew about NSMakeRect, NSMouseInRect, NSOffsetRect and many others but somehow missed the functions that aid in recalculating NSRect geometry.

Answer 1

I've found NSStringFrom*() helpful when logging structs like CGRect, CGPoint, etc.

You can find a comprehensive overview at Apple's Foundation Functions Reference (Wayback Machine link).
