Question

I got a NSData that contain bytes like <00350029 0033> with length 6, is there any correct way to split the bytes to array somehow like (00, 35, 00, 29, 00, 33) ?

Answer 1

NSData *data = ...;
NSMutableArray *bytes = [NSMutableArray array];
for (NSUInteger i = 0; i < [data length]; i++) {
    unsigned char byte;
    [data getBytes:&byte range:NSMakeRange(i, 1)];
    [bytes addObject:[NSString stringWithFormat:@"%x", byte]];
}
NSLog(@"%@", bytes);

(Assuming you want the bytes as a hex string representation, as in your example. Otherwise, use NSNumber.)
