Question

I have a NSData object which is supposed to work like a byte array.

I need to get the 1st and 2nd bytes in the NSData, but don’t know how.

If I have a byte array in Java, I can easily get those via barray[0] and barray[1], but how do I do it for NSData?

Thanks

Answer 1

NSData *data = [NSData dataWithBytes:"abc" length:3];
const unsigned char* bytes = [data bytes];
NSLog(@"%c %c",bytes[0],bytes[1]);
