RE: newbie q's - Storing arrays of non-objects

That is how I began, but I had an array of arrays of NSNumbers and it was
nasty looking doing something like:
theID = [[[mySymbolArray objectAtIndex:theSymbol] objectAtIndex:theElement]
longValue];

looking at it now it isn't so bad...
thanks!

You could store them as NSNumbers using [NSNumber numberWithLong:] or is
this not an option?

Hi,
Im writing some software where I need to store an array of 'symbols', where
each symbol is an array of 3-8 Long's. As far as I can tell I cant have an
NSArray of long[]'s because they aren't objects and dont have
reference-counts etc etc. So at the moment I am storing each symbol in an
NSData object, but this feels a bit heavy handed, especially when it comes
to reading out 4 bytes at a time to get a long.
Is there a better way to do this? What is the best way to store arrays of
non-objects? (ps is non-object = atomic ?)
Thanks
oli
