Question

I have a struct defined like follows as part of an object. I’m trying to encode this for use with NSCoder with the aim of saving as well as Undo/Redo functionality.

struct myCol {     float rd;     float grn;     float blu;     float alp; } toolColor; 

So, there are methods to encode e.g. -encodeBool:, -encodeFloat:, -encodeObject: etc. But how do you do this for a struct?

I think you should consider you struct myCol as memory buffer and encode it by something like encodeBytes function. Buffer length = size of your struct
