Hi all, I'm just getting started with Cocoa and I'm trying to implement hash and isEqual: methods according to the recommendations in the coding guidelines.
To implement a hash method I would normally just hash the receiver's instance variables together and xor the result, but this only works if the instance variables are objects. However my instance variables are NSPoints, which are defined as structs, not objects. The C programmer in me wants to cast the floats into integers and hash those, but we are in a 64-bit world now, and I assume that 32-bit algorithms may not give a good result. Maybe I'm trying too hard, but it's important for what I'm doing that I don't have a lot of collisions so I want a good quality hash function. What's the standard way of hashing non-object values in Cocoa?
