title: NSURL Connection Warning "Unused variable"
body: <p>I am getting data from an NSURL connection like below. The code works, but I get a compiler warning that says "Unused variable strResult." </p>
  
  <p><strong>I don't actually need to use what is returned. I just need the URL to be executed.</strong></p>
  
  <p>How can I go about modifying this to get rid of the warning?</p>
  
  <pre><code>NSString *strURL = [NSString stringWithFormat:@"http://www.site.com/file.php?id=%@", id];
  
  NSData *dataURL = [NSData dataWithContentsOfURL:[NSURL URLWithString:strURL]];
  
  NSString *strResult = [[NSString alloc] initWithData:dataURL 
  encoding:NSUTF8StringEncoding];
  </code></pre>
  
  <p>Thank you!</p>
