Depends a bit on the contents of the data you want to retrieve. As an example, if the data can be interpreted as a UTF8-encoded string you could use:

NSString *data = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:NULL];

If you just want to get bytes of data without interpreting as a string you can also do this:

NSData *data = [NSData dataWithContentsOfURL:url];

You then have all the data available to parse out however you need to.

The NSData class has a method 'dataWithContentsOfURL' that will enable you to retrieve data from a webserver.

Sample code:

NSData* someData = [NSData dataWithContentsOfURL: [NSURL URLWithString:someURL]];
