Either one will work. Lipo can link the binary inside the framework and a simple static library

What I did is to create a static library project, and a framework project. Set the static library target to be either device or simulator (using sdk iphoneos or iphonesimulator. Add the Universal Framework script into the framework project to build the static library with the other sdk and put the fat binary to the framework. Also copy needed headers to the framework project. The framework do not need to compile anything.
