Hi,
I will use NSKeyedArchiver to create a lot of NSData objects before
writing to file.
I can't write one whole NSData to file because i have to write in GBs
and also have to show the progress bar.
Thanks for the reply,
Nick

Sorry to duck your question, but are you sure you don't want
NSKeyedArchiver and similar classes?

Hi,
I am creating a file with:
NSFileManager *fileManager = [NSFileManager defaultManager];
[fileManager createFileAtPath:path contents:nil attributes:nil];
===========
then I got a fileHandle as:
NSFileHandle *fileHandle = [NSFileHandle
fileHandleForWritingAtPath:path];
===========
NSFileHandle has the method:
- (void)writeData:(NSData *)data
=====================
but i want to write the length of (NSData *)data, before I write
it to file because I will be writing a lot of NSData to the file,
so that I will be able to read the length first and then read the
following NSData.
SO how can I write the length which is an integer to file before I
write the NSData.
Thanks,
Nick
