Read a text file line by line? - jdunehew - Dec 13, 2011 09:47 PM
Is it possible to read a text file line by line or some way split up the lines once read out of a text file?
Thanks

Yes. For example, http://www.opengroup.org/sud/sud1/xsh/fgets.htm

Thank you very much, I forgot to note that I'm using Objective C and this is for iOS.

If you can't get ThemsAllTook's answer to work I'm quite sure you can find what you are searching for here:
NSString Class Reference
Or by googling: "Cocoa file to string" & "NSString split into lines"

if you know that the lines are all of the same length (suppose 30 chars) you can use fscanf("%30c",&string);

I ended up figuring it out. I just used this:
NSArray *lines = [fileContent componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]];
Below it I loop through the array and separate it out into strings.

If your input file is large enough, you will also want to consider using an input stream buffer. This will allow you to read only a portion of the file so that you don't dump the entire file into memory at once.
