Question

I am reading a text file from a URL and want to parse the contents of the file into an array. Below is a snippet of the code I am using. I want to be able to place each line of the text into the next row of the array. Is there a way to identify the carriage return/line feed during or after the text has been retrieved?

NSURL *url = [NSURL URLWithString:kTextURL];
textView.text = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding                        error:nil];

When separating by newline characters it’s best to use the following procedure:

NSCharacterSet *newlines = [NSCharacterSet newlineCharacterSet];
NSArray *lineComponents = [textFile componentsSeparatedByCharactersInSet:newlines];

This ensures that you get lines separated by either CR, CR+LF, or NEL.
