title: Printing NSData using NSLog
body: <p>How can I print the contents of an NSData object using NSLog:</p>
  
  <pre><code>-(void) post:(NSString*) msg to:(NSString*) link{
      NSString *myRequestString = [NSString stringWithFormat:@"message=%@", msg];
      NSData *myRequestData = [NSData dataWithBytes: [myRequestString UTF8String] length: [myRequestString length]];
      NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL: [NSURL URLWithString: link]]; 
      [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"content-type"];
      [request setHTTPMethod: @"POST"];
      [request setHTTPBody: myRequestData];
      NSData *returnData = [NSURLConnection sendSynchronousRequest: request returningResponse: nil error: nil];
      NSLog("%@", *returnData); //doesn't work
  
  }
  </code></pre>
  
  <p>I would like to print the contents of *returnData...</p>
