Sharing Compiled Code: Building Static Libraries in XCode for the iPhone

On December 3, 2008

It’s not impossible to share a binary of some of your code, however! iPhone Developer Brian Stormont has written a tutorial on building static libraries with the iPhone SDK. He had developed a streaming audio library that he was willing to share (without source) with a client and compiled it into a static library so that they could link it directly into their own app.

    There are also some great sqlite libraries for the iPhone out there, but they all seem to be distributed as source not as static libraries (the best of which IMHO is fmdb by gus mueller). It’s good to know though that libraries could be distributed either way.

    If the library is being distributed as an Xcode project (i.e., with source code) using a cross-project reference to build the static libraries “on demand” can be handy. I’ve got a tutorial on this at in case it’s helpful for anyone else.
