Hi guys,
Im having a little problem here with reading NSData from a file, this is the
line that starts the reading:
NSData *fileData = [NSData dataWithContentsOfFile:path
options:NSDataReadingMappedAlways | NSDataReadingUncached error:&error];
I wanna it mapped always and uncached because I don't wanna read the entire
file, just some pieces of it (small pieces), so, if the user is acessing a
file from an external drive, and the file has 8gb, I only wanna read 64kb,
so, I don't wanna read it all just for 64kb.
Giving that, sometimes, I'm receiving some crash reports, by bad memory
access, I mean it should be the map got unavailable (maybe removed the drive
or something), and the software crashes...
There is any way to handle it? Any kind of try/catch that I can do while
reading the bytes, so, I can recover from the error?
