Draw vertical separator on UITableViewCell

I had a plain styled UITableView, and it's cells are a subclass of UITableViewCell.

In the cell subclass I overrode drawRect to put this drawing code in (for a vertical separator):

CGContextRef c = UIGraphicsGetCurrentContext();
CGContextSetStrokeColorWithColor(c, [[UIColor grayColor] CGColor]);
CGContextBeginPath(c);
CGContextMoveToPoint(c, self.frame.size.height + 0.5f, 0);
CGContextAddLineToPoint(c, self.frame.size.height + 0.5f, self.frame.size.height);
CGContextStrokePath(c);

It worked great. However I have now changed the tableview style to grouped. The line simply isn't drawn. Although settings a breakpoint shows the drawRect method is called.

I would like to avoid subclasses UIView just to draw a small line, especially as I've already subclassed the tableview cell and I just want to draw on the cell. So why does the code suddenly stop working on a grouped tableview?

It is not good idea to override drawRect in UITableViewCell subclasses. If you do not want to set custom cell's backgroundView, then you can just add simple UIView of 1px width. 

UIView* vertLineView = [[UIView alloc] initWithFrame:CGRectMake(80, 0, 1, 44)];
vertLineView.backgroundColor = [UIColor redColor];
[self.contentView addSubview:vertLineView];
