How to customize tableView separator in iPhone

Question

By default there is a single line separator in uitableview.

But I want to put my customized line as a separator.

Is it possible? How?

On a retina display, even drawing a 0.5 unit line will result in a two-pixel line, due to anti-aliasing. To render it as a single pixel on both displays, shift it up one quarter of a unit:

UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(0, self.contentView.frame.size.height - (1.0 - 0.25), self.contentView.frame.size.wi
lineView.backgroundColor = [UIColor colorWithRed:(230.0/255.0f) green:(233/255.0f) blue:(237.0/255.0f) alpha:1.0f];
[self.contentView addSubview:lineView];
