BRLineReader is a class for iOS and OS X that reads text data line by line.
Data can be read from file or from a supplied NSData object. If reading from file it will be represented by a memory-mapped data object.
All ASCII based text encodings and variable length encodings like UTF-8 are supported, but multibyte encodings like UTF-16 are not since the line delimiter must be represented with a single byte.
Add the BRLineReader.[hm] files to your project and #import the header file.
NSString *path = @"/path/to/file";
BRLineReader *lineReader = [[BRLineReader alloc] initWithFile:path encoding:NSUTF8StringEncoding];
NSString *line = nil;
while ((line = [lineReader readTrimmedLine])) {
// Do things with line...
}The demo app has not been implemented yet, but it can be used to run the unit tests.
If this NSData based solution is not to your liking the same functionality can be implemented with NSInputStream or NSFileHandle.
