Hi Everyone, I am new to this forum and newish to programming in Objective C, but have a few application ideas in mind that I want to try and make a start on. One of these is an application that involves compressing and optimising a text file (UTF8 encoded) into an NSData object of a much reduced file size. I have read about the GZIP and ZLIB compressions, but these seem to only be the same as a normal zip procedure. What I was hoping to do was convert the text file to a different binary encoding and then compress it, if possible. It may be the case that this kind of thing just isn't that straightforward and if so feel free to tell me up front. It couldmsave me a lot of wasted time.... Any help you guys and gals can give me would be really appreciated.
