I am wondering what the best way to read a text file, line by line,
when the file size is much larger than available memory.
For very large files you probably want to use NSFileHandle. With the
method readDataOfLength: you can read the file in chunks and then
parse through for the line endings.
I also find the non existence of a readLine type mechanism quite
strange. Either way, this has given me enough to go on so thanks for the
help!
I can just read in large blocks, read each line within the large block,
then use the index of the last line ending to fetch the next large block.
Sounds like a worthwhile blog entry (:
Best regards,
Jacob
