I'm working on a cocoa app in which i'd like to compress a chunk

I notice that zlib is installed as part of panther, so was
thinking that a category on NSString that made use of zlib would
be a decent approach, so i could call a method like
stringByCompressingString:options: or something similar.
I've never done this sort of thing before, so i thought i would
check here to see if:
a. this approach was wrong-headed.
b. something like this already exists somewhere.
Myself, I would launch bzip and pipe the data through it. YMMV, of
course.
Anyroad, if you are about to write this, I guess you want rather
compress NSData than NSStrings (adding perhaps just a convenience
NSString category which would convert self to NSData and then use
the compression).
OmniFoundation has an NSData category for compressing/decompressing
with gzip or bzip2. Seems to work quite well in my usage, but
Ondra's solution probably requires the least code.
