title: UIView vs core graphics
body: <p>I have a UITableViewCell subclass which draws a rectangular vertical line of 5px width and height of 100. I am using a UIView for this. However I am a bit afraid o the performance of using UIView. Is it better to use core graphics for stuff like this instead? If yes then how would you convert the following:</p>
  
  <p>UIView *vLine = [UIView alloc] initWithFrame:CGRectMake(10, 0, 5, 100)];
  [self addsubView:vLine]
  [vLine release]</p>
  
  <p>How do you convert the above using CG?</p>
