Hi folks,
I've got an app that needs to keep track of version numbers (eg.
"10.6.2") of things, and needs to be able to sort by these too. Is
there a class in Cocoa that handles this?
I could have sworn I heard mention of it in a previous WWDC (probably
about 10.5), but all attempts at searching result in a load of pages
pointing me towards Info.plist to get the version number :-/
The other people who I went with think I'm dreaming it...
If one doesn't exist, then I'm guessing doing an NSString subclass
would be the order of the day (so that I can support / sort
alphanumeric version "numbers" such as 10C540, or 1.0.1.2b), and then
scanning for each period or change from number <-> letter, to break
the version number down into its component parts (eg. so that 10C540
ends up being {10, C, 540}?
Merry Christmas to all who celebrate it, and thanks in advance for any
help you can give,
Ken
