maybe it's just me, but code size on things I've written seems really huge... not in terms of the objective-c code, but the compiled app: for example, the executable for apple's TextEdit is about 112KB here, but apps that I've written that are similar, but do much much less come in around 1MB for the executable size.
What's going on? is apple getting away with more by using carbon? or is it just that they have a couple tricks up their sleeves that they don't want to share?

statically linking versus dynamic linking?
poor coding? (no offense, it's a legitimate cause for large executables).

signatures are a waste of bandwidth
especially ones with political tripe in them.

poor coding? nah... see, cause apple includes the source code for text edit in the dev tools (10.2, not Xcode) that I'm using, and compiling it results in a application package aroud 2.2 MB in size (the shipped TextEdit is 684kB or so)
what's the difference between static and dynamic linking? which is better for code size? how do I set things up to use that option?

You have debugging code in yours. If your build target a "development build" or a "deployment build."?

yeah, you can either run "strip" on the executable file or set it to deployment mode.

You should use Deployment style AND strip.

In XCode doesn't deployment strip the executable? I know there's an option to.

thanks, that's much better... just as a side note though, I couldn't tell that strip made any difference, but having projectbuilder not generate debug symbols and setting it in deploy mode worked great.
thanks again!
