Contents from url to string

Question

NSString *urlAddress = [NSString stringWithFormat:@"http://www.domain.com?input=%@",[alertView textFieldAtIndex:0].text];
NSURL *myUrl = [NSURL URLWithString:[urlAddress stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSString *openURL = [NSString stringWithContentsOfURL:myUrl encoding:NSUTF8StringEncoding error:NULL];
NSLog(@"%@",openURL);

openUrl is always returning (null), probably because of the encoding, but I don't know how to fix it.

The method has a means of giving you errors and your not using it `error:NULL];`, check this first — Simon McLoughlin, May 27 '14 at 10:20

Double check these three things:

Check that the URL which you are pointing to is a valid URL. The null value could be a result of an invalid URL.
Catch the NSError which the stringWithContentsOfURL throws. That will give you some insight on what is wrong.
Like you suspect, try changing the string encoding.

NSError *error;
NSString *urlString = [NSString stringWithFormat:@"http://www.domain.com?input=%@", stringVariable];
NSURL *urlAdress = [NSURL URLWithString:urlString];
NSString *urlContent = [[NSString alloc] initWithContentsOfURL:urlAdress encoding:NSUTF8StringEncoding error:&error];
NSLog(@"%@", urlContent);

This works fine, the problem was an failing internet connection.
