UITableView separator gone when using viewForFooterInSection - ios

Question

UITableView showing separator even there is no rows. But when I use viewForFooterInSection the separator is gone. I want it to keep showing up. What should I do ?
Here is my code when I add footer in it :
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 3;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath; {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"s"];
cell.textLabel.text = [NSString stringWithFormat:#"%d", indexPath.row + 1];
cell.textLabel.textAlignment = NSTextAlignmentCenter;
return cell;
}
// -------------------------- footer code start here --------------------------
- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {
return 40;
}
- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section {
UIView *view = [[UIView alloc] initWithFrame:CGRectZero];
view.backgroundColor = [UIColor grayColor];
UILabel *title = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 40)];
title.text = #"footer here";
title.textAlignment = NSTextAlignmentCenter;
title.textColor = [UIColor whiteColor];
[view addSubview:title];
return view;
}

Answer 1

this github project may give you some advices:
CLTableWithFooterViewController
Of course need some change if you would like the footer always display on the screen even if with a lot of cells.

Answer 2

remove - (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section
and - (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
use this code to keep the footer down (but always visible) and keep the separator:
#implementation tableView {
__weak UIView *_staticView;
}
- (void)viewDidLoad {
UIView *staticView = [[UIView alloc] initWithFrame:CGRectMake(0, self.tableView.bounds.size.height-50, self.tableView.bounds.size.width, 50)];
staticView.backgroundColor = [UIColor redColor];
//add other code for UILabel here
[self.tableView addSubview:staticView];
_staticView = staticView;
self.tableView.contentInset = UIEdgeInsetsMake(0, 0, 50, 0);
}
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
_staticView.transform = CGAffineTransformMakeTranslation(0, scrollView.contentOffset.y);
}
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
// this is needed to prevent cells from being displayed above our static view
[self.tableView bringSubviewToFront:_staticView];
}

I guess you just have a single section,right? Before you using viewForFooterInSection,it just fills blank cells all the way down.But when you call viewForFooterInSection,tableview will put a footer at the end of the section.Since you don't have the second section,it stops draw any cells.So you can make a blank second section,it will fill blank cells to the second section.
