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.

I know there are helper functions like stringWithContentsOfFile:encoding:error:, but this implies having to load the entire file in memory. Google has not been of much extra help here.

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. _______________________________________________
