I have the following code, which is a category on NSData. It is always
called on especially designated NSData objects with four bytes.
- (NSData *)resolve {
unsigned char *buf = [self bytes];
const unsigned char *newBytes[4] = { (buf[3] - 0x08), buf[2], buf[1],
buf[0] };
for (int i = 0; i < 4; i ++) {
NSLog(@"%02X", newBytes[i]);
}
NSData *ret = [NSData dataWithBytes:newBytes length:4];
return ret;
}
The for statement logging the individual bytes is exactly as expected.
However, the new data object ret is <00000000>. I couldn't really find
an answer on google, probably because it's a simple answer I'm
missing, so I asked here. Thanks for any help.
