hello list,
i have a problem i keep on working around, and its time to try and get
a proper solution: does anybody know of an efficient way to check
whether any object in a structure input has changed?
the [didValueChange...] method seems to only check whether the actual
NSDict/NSArray object has changed, and not any of the objects in their
collection. i guess i'd like to compute a simple hash derived from the
all the object pointers, but my cocoa starts to look distinctly
unoptimised when its collections-of-collections-of-collections.
thanks,
toby
