iphone - What is the "stringWithContentsOfURL" replacement for objective C?

Question

I found a tutorial on the net that uses the stringWithContentsOfURL command that is now deprecated as of iPhone OS 3.0. However I can't find out what I'm meant to use instead, and how to implement it.

Below is the code surrounding the stringWithContentsOfURL line in case you need it for reference.

NSString *urlString = [NSString stringWithFormat:@"http://maps.google.com/maps/geo?q=%@&output=csv", 
     [addressField.text stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSString *locationString = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlString]];
NSArray *listItems = [locationString componentsSeparatedByString:@","];

Thanks.

Thanks Greg, but for all those other beginners here is an example

NSError* error = nil;
NSString* text = [NSString stringWithContentsOfURL:TheUrl encoding:NSASCIIStringEncoding error:&error];
if( text )
{
    NSLog(@"Text=%@", text);
}
else 
{
    NSLog(@"Error = %@", error);
}
