How can I read a file a line at a time (i.e. getline)? I'm trying
to do this in a Cocoa Framework.
Try using NSFileHandle to read a file until a line feed is
encountered. There's no built-in method of stopping at a character,
but you could always read it in byte by byte.
Or you could read the file into a string and split it with \n,
although Nick's method is probably more efficient:
NSError *error;
// use the proper encoding if it's not UTF-8
NSString *string = [[NSString alloc] initWithContentsOfFile:path
encoding:NSUTF8StringEncoding error:&error];
if( !string ) { /* do something with the error */ }
NSArray *lines = [[string componentsSeparatedByString:@"\n"]
retain]; // assuming line terminator is \n for this file
[string release];
for( NSString *line in lines ) {
// process each line
}
[lines release];
