A JSON object mapping iOS device model codes (e.g. iPad2,1) to their respectively marketing names (e.g. iPad 2).
The data is mainly sourced from here.
The following C code prints the device model code:
#include <sys/sysctl.h>
size_t size;
sysctlbyname("hw.machine", NULL, &size, NULL, 0);
char result[size];
sysctlbyname("hw.machine", result, &size, NULL, 0);
printf("%s\n", result);
// result is a typical C string that can be passed to [NSString stringWithUTF8String:result];
Thanks to vijaymadhavan for adding more detail to each row. (See pull request #2)
