Project 2 is a static library. Project 1 is your app.
- Close Project 2. Yes, you have to do this.
- Using drag and drop or add files, add Project 2 to Project 1.
- In the root directory for Project 1, add a soft link to the directory where Project 2's sources are kept. So in this example, I'm in /myMillionDollarProjects/UsingConfusionUtil and I type
ln -s /myMillionDollarProjects/ConfusionUtil ConfusionUtil
- Exclude this link from git by adding the name of your soft link to your .gitignore (in this case, ConfusionUtil).
- In User Header Search Paths for Project 1, add the name of the soft link (in this case, ConfusionUtil).
- Check the box to the left of that which means "recursive." This just adds a forward-slash followed by two asterisks to the name (so in this case, I see ConfusionUtil/**).
- In Build Phases for Project 1, under Link Binary With Libraries, add the .a for Project 2.
- In your Other Linker Flags, add -ObjC with the leading dash (otherwise categories won't work)
- Try to reference something from Project 2 in Project 1. Don't just compile, but also run to make sure it's all correct.
Note: If you need to use static libs, you can figure all these issues out and more, but personally the distribution provision cert issues proved to be too much.
