char array to [NSString stringWithFormat:]

Question

I have this code in my code (md5 hashing)

unsigned char result[16];
// fill result with data
[NSString stringWithFormat: 
              @"%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x",
              result[0], result[1], result[2], result[3], 
              result[4], result[5], result[6], result[7],
              result[8], result[9], result[10], result[11],
              result[12], result[13], result[14], result[15]
              ];

Is there some faster way, how to push whole array in NSString than this code?

That's the fastest way to hexify 16 characters into an NSString. If you do this often, wrap it up in a function so you only have one copy of the code. :)
