Question

I need to store single bytes in objective c. So I may have a class interface like this:

@interface NAD : NSObject

@property (...) ... byte;

@end

I started off with uint8_t pointers, but this was getting difficult because they’re actually 4 bytes, or something.

So I switched to using NSData. But NSData deals in “bytes” (plural). This isn’t a problem necessarily, but is getting quite fiddly having to convert between all the time.

So is there a better way to store 1 byte (8 bits) in objective c variables?

Many thanks

Answer 1

Why uint8_t * and not simply uint8_t?

@property (assign) uint8_t byte;

To wrap it into an NSData object:

uint8_t b = object.byte;
NSData *d = [NSData dataWithBytes:&b length:1];
