Can you define your own export macros instead of reusing those from
Foundation/Foundation.h.

See
https://code.google.com/p/chromium/codesearch#chromium/src/base/base_export.h...
for an example (you can probably remove all Win32 support).

This is a template file generated by Xcode based on the framework name
(iOSFramework).  I'm going to leave as is since this is exactly what Xcode does.
