To make a reusable library on the iPhone, you should create a new target of type "Cocoa Touch Static Library". Add the source files that will go to make up the library to this new target, and remove them from your application(s)'s target(s). Now add the new target as a dependency of each application target (Ctrl-click the app target, get info, add direct dependency) and also add the library product (called yourtargetname.a) to the "link libraries and frameworks" phase of the app.
