@dhanya : change this style to:
<pre>
  CGRect desLabelFrame = CGRectMake(10,
                                    titleLabel.frame.origin.y + titleLabel.frame.size.height + 20,
                                    self.view.frame.size.width - 20,
                                    20);
  UILabel* desLabel = [[UILabel alloc] initWithFrame:desLabelFrame];
</pre>
