I am currently learning Objective C programming using Xcode. I am wondering how to have multiple main programs, i.e. source members with main method in it, in a single project? It is a bit inconvienient to put just one in each project, as I would have to create tons of them through my learning process. Or is there any better way to do it? All I want is to place multiple independent executable programs in a single project, though I only need to run on each time. Thanks a lot.
This is much more trouble than it's worth. Just create tiny test projects. I've got a huge directory of them that I throw away from time to time. I also constantly re-create a project called "Test" for building little projects.
For really, really tiny things, I do sometimes create a simple test.m file that has its own main and compile it by hand:
gcc -framework Foundation -o test test.m
But in that case I don't bother with Xcode.
EDIT You of course could replace gcc above with clang. For projects so small that I'm doing this, it hasn't been worth changing my muscle memory....
