I am currently putting 320 to 480 character long NSString *

I guess I could use an int array, but I'm looking to speed up my
app and reduce storage. Is it possible to create a BOOL array that
can be put into an NSMutableArray?
Or use NSMutableData objects with 1 byte for each 0 or 1 value. You
can then get the BOOL values as 'data.bytes [index]', set them with
'data.mutableBytes [index] = someBool' and resize the array with
'data.length = someLength'. In terms of source code, that's about as
minimalistic as it gets without being pure C.
Very nice. This is simple, it performs well, and depending on how
you're storing the data, might possibly cut down the storage space of
your array significantly (for example if you're using a plist).
My only question would be how many of these arrays you have and how
often you're stuffing booleans into them, and whether you're sure
operations on this array are actually taking a noticeable amount of
time.
