Hi,
I think I understand how to write data on a disk using archive and
serialization mechanism, but how about this case?
I just want to write a short value, a long value and a double value
in this order. I don't want to write anything but them.
And I'd like to use document-based application to write the data
onto a disk.
Any suggestions would be welcomed.
Thank you,
Norio Ota
Create an NSMutableData Object. Append your value using -
appendBytes:length:
Use -writeToFile:options:error: to save your data.
Do not forget to swap yout bytes if needed.
If you want to append a short using Big Endian order, you can do
something like this:
short myshort = 4124;
myshort = OSSwapHostToBigInt16(myshort);
[myData appendBytes:&myshort length:sizeof(myshort)];
