UITableView Section Footer overlaps when scrolling

Question

I have a UItableview for which i had the section header & footer programatically.

Initially i had problems with the sectio header overlapping on scroll which i solved using the scrollViewDidScroll delegate as

- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
    heightForHeader = 40.0;
    if (scrollView.contentOffset.y<=heightForHeader&&scrollView.contentOffset.y>=0) {
        scrollView.contentInset = UIEdgeInsetsMake(-scrollView.contentOffset.y, 0, 0, 0);
    } else if (scrollView.contentOffset.y>=heightForHeader) {
        scrollView.contentInset = UIEdgeInsetsMake(-heightForHeader, 0, 0, 0);
    }
}

now the next issue is with the section footer that is overlapping while scrolling.

Can you help me with this?

Answer 1

Do you set your custom heights for header and footer?

Your table view delegate should implement this methods:

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section

- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section

which should return appropriate values.

If you return smaller values then your header and footer views have, then they may overlap.

You are looking for this: I have tested it and it works

    CGFloat sectionFooterHeight = 40;
    CGFloat tableViewHeight = self.tableView.frame.size.height;

    if (scrollView.contentOffset.y=tableViewHeight) {
        scrollView.contentInset = UIEdgeInsetsMake(0, 0,-scrollView.contentOffset.y, 0);
    } else if (scrollView.contentOffset.y>=sectionFooterHeight+self.tableView.frame.size.height) {
        scrollView.contentInset = UIEdgeInsetsMake(0, 0,-sectionFooterHeight, 0);
    }
