I\'m working on a project which shall contain two targets. One for building a Framework to use in Mac development and another to create a static library to use in iPhone dev
It's actually not that bad. Just create a second target of the appropriate type and then change the "Base SDK" build setting. Then make sure to add all the necessary files. If you want to build both at the same time, create an aggregate target. For a practical example see my project SSPromise.
