Based on my limited experience building for OS X, I think it would be
easier to use a framework with Xcode. You can use cmake to build a TagLib
framework with -DBUILD_FRAMEWORK=ON (see the INSTALL file).

With this I can't help directly, I have no experience with Obj-C, but have
a look at some of Stephen's code that uses TagLib:
