Subject: Re: Reading one line at a time using NSFileHandle



If this is a small file, just create an NSString and iterate over lines.
Here is a simple snippet that count number of lines in a string. You can modify it for your purpose.

NSString *string;
unsigned numberOfLines, index, stringLength = [string length];
for (index = 0, numberOfLines = 0; index < stringLength; numberOfLines+ +)
index = NSMaxRange([string lineRangeForRange:NSMakeRange(index, 0)]);

I read the CocoaBuilder thread to no avail. fgets won't work in my case because my text file contains special characters which fgets mangles.

BTW, my file is not large - less than 1K. And I know it's encoding - MacRoman. And I know the line endings "/n".

But what I don't know is which API to use to read non-ASCII lines of text one at a time from one file, and write them to another file after processing each one.

One would think Cocoa would have something like fgets but that works with any encoding.

Is there a way to read one line of a text file at a time using NSFileHandle
(the way fgets does)?

Is it my imagination or did we not just have a big thread about this...?
