title: stringByAppendingString
body: <p>I am using Xcode 4.2 storyboard.
  I am stuck in this concatenation. Is this right? Where in the code i've to modify?
  actually i want to display a new tableview depending on the variable passed ("row") from previous tableview.
  Any help appreciated.</p>
  
  <pre><code>self.newrow =row;// row is the variable passed from previous tableview
  
  NSString *urlString = [NSString stringWithFormat: @"http://ipaddress/iphone.php?id="];
  
  NSString *urlStr=@"";
  urlStr=[urlString stringByAppendingString:newrow];
  
  NSURL *url = [NSURL URLWithString:urlStr];
  NSURLRequest *request = [[NSURLRequest alloc] initWithURL: url];
  NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
  [connection release];
  [request release];
  </code></pre>
