NSString stringWithContentsOfURL is deprecated. What should I do?

I've written some code that uses stringWithContentsOfURL, but it turns out that it is now deprecated. Can you help me replace it? Here's my code:

NSString *locationString = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlString]];
NSArray *listItems = [locationString componentsSeparatedByString:@","];

Additionally, can someone have some sample code to show how it works? What encoding was the original code done in (in my 2 lines above)?

I want to maintain compatibility so what should I choose for the encoding? What does error mean and what is it used for?

Use stringWithContentsOfURL:encoding:error:

EDIT: Here's your code using the above method:

NSError *error = nil;
NSString *locationString = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlString] encoding:NSUTF8StringEncoding error:&error];
NSArray *listItems = [locationString componentsSeparatedByString:@","];

You can change NSUTF8StringEncoding accordingly for whatever data you're importing.

The NSString reference says this:

Use stringWithContentsOfURL:encoding:error: or stringWithContentsOfURL:usedEncoding:error: instead.
