NSString *const kUITablewViewCellSeparatorLayerName = @"kUITablewViewCellSeparatorLayerName";

@implementation UITableViewCell (MyAdditions)

-(CALayer *)separatorLayer
{
    for (CALayer *sublayer in self.layer.sublayers)
    {
        if ([sublayer.name isEqualToString:kUITablewViewCellSeparatorLayerName])
            return sublayer;
    }
    return nil;
}

-(CALayer *)newSeparatorLayer
{
    CALayer *separatorLayer = [CALayer layer];
    separatorLayer.name = kUITablewViewCellSeparatorLayerName;
    separatorLayer.frame = CGRectMake(0, self.bounds.size.height - 1, self.bounds.size.width, 1);
    separatorLayer.backgroundColor = [UIColor whiteColor].CGColor;
    [self.layer addSublayer:separatorLayer];
    return separatorLayer;
}

-(UITableViewCellSeparatorStyle)cellSeparatorStyle
{
    CALayer *separatorLayer = [self separatorLayer];
    if (separatorLayer == nil)
        return UITableViewCellSeparatorStyleNone;
    else
        return UITableViewCellSeparatorStyleSingleLine;
}

-(void)setCellSeparatorStyle:(UITableViewCellSeparatorStyle)separatorStyle
{
    CALayer *separatorLayer = [self separatorLayer];
    switch (separatorStyle)
    {
        case UITableViewCellSeparatorStyleNone:
            [separatorLayer removeFromSuperlayer];
            break;
        case UITableViewCellSeparatorStyleSingleLine:
            if (separatorLayer == nil)
                separatorLayer = [self newSeparatorLayer];
            break;
        default:
            @throw [NSException exceptionWithName:NSStringFromClass([self class]) reason:@"Unsupported separatorStyle" userInfo:nil];
            break;
    }
}

-(UIColor *)cellSeparatorColor
{
    CALayer *separatorLayer = [self separatorLayer];
    return [UIColor colorWithCGColor:separatorLayer.backgroundColor];
}

-(void)setCellSeparatorColor:(UIColor *)separatorColor
{
    CALayer *separatorLayer = [self separatorLayer];
    if (separatorLayer == nil)
        separatorLayer = [self newSeparatorLayer];
    separatorLayer.backgroundColor = separatorColor.CGColor;
}

@end

Now you can do things like

UITableViewCell *cell = ...
cell.cellSeparatorStyle = UITableViewCellSeparatorStyleSingleLine;
cell.cellSeparatorColor = [UIColor orangeColor];
