Question

I have a UITableView and I have only 3 rows in it, and I can see those 3 rows. The problem is the cells that are empty: I can see lines there. I don’t want to see those lines.

Any idea how to remove those lines?

Below is image for what I am looking for.

You can hide UITableView‘s standard separator line by using any one of the below snippets of code.
The easiest way to add a custom separator is to add a simple UIView of 1px height:

UIView* separatorLineView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 1)];
separatorLineView.backgroundColor = [UIColor clearColor]; // set color as you want.
[cell.contentView addSubview:separatorLineView];

OR

    self.tblView=[[UITableView alloc] initWithFrame:CGRectMake(0,0,320,370) style:UITableViewStylePlain];
    self.tblView.delegate=self;
    self.tblView.dataSource=self;
    [self.view addSubview:self.tblView];

    UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 10)];
    v.backgroundColor = [UIColor clearColor];
    [self.tblView setTableHeaderView:v];
    [self.tblView setTableFooterView:v];
    [v release];

OR

- (float)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {
    // This will create a "invisible" footer
    return 0.01f;
}

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{
    // To "clear" the footer view
    return [[UIView new] autorelease];
}

OR

And also check nickfalk’s answer, it is very short and helpful too.
And you should also try this single line,

self.tableView.tableFooterView = [[UIView alloc] init];

Not sure but it’s working in all the version of iOS that I checked, with iOS 5 and later, up to iOS 7.
