title: UILabel text blinking when showing file progress text
body: <p>I show file transfer progress in a label. But when the <code>fileprogress</code> data string appears than <code>directionstring</code> text blinking according to its position. How to stop this blinking of appended string?</p>
  
  <pre><code>directionstring = @"uploaging file";
  fileprogress = transferring rate EX.(25.00 MB of 50.00 MB);
  message = [message stringByAppendingString:[NSString stringWithFormat:@"%@%@",fileprogress,directionstring]];
  progressLabel.text = message;
  </code></pre>
