دوست عزیز، من فایل هدر (به زبان C) رو پیدا کردم ولی اولاً نیاز به یکسری فایل دیگه بعنوان AppKit داره که باید استفاده کنید : AppKit (http://www.koders.com/c/fid66AF92C36949711A895696191678FBA1FE20C1F4.aspx) ثانیاً سینتکس عجیبی داره، @interface و @end و - و ... که من نمیدونم چخ معنی میدن! احتمالاً تو AppKit اینجور سینتکس ها #define شده :
