#import <Foundation/Foundation.h>
static NSString * const hexString = @"850210";

int main (int argc, const char * argv[])
{
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

    uint8_t         data[3]={0};
    const char      * theUniChar = hexString.UTF8String;

    for( int i = 0, c = (int)strlen(theUniChar)/2; i < c && i < sizeof(data)/sizeof(*data); i++ )
    {
        int     theNum = 0;
        sscanf( theUniChar + 2*i, "%2x", &theNum );
        data[i] = theNum;
    }

    printf( "{%x,%x,%x}\n", data[0],data[1],data[2] );


    [pool drain];
    return 0;
}
