Is it possible to disable floating headers in UITableView with UITableViewStylePlain?

Question

I\'m using a UITableView to layout content \'pages\'. I\'m using the headers of the table view to layout certain images etc. and I\'d prefer it if they didn\'t

Answer 1

There is another tricky way. The main idea is to double the section number, and first one only shows the headerView while the second one shows the real cells.

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return sectionCount * 2;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    if (section%2 == 0) {
        return 0;
    }
    return _rowCount;
}

What need to do then is to implement the headerInSection delegates:

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
    if (section%2 == 0) {
        //return headerview;
    }
    return nil;
}

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
    if (section%2 == 0) {
        //return headerheight;
    }
    return 0;
}

This approach also has little impact on your datasources:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    int real_section = (int)indexPath.section / 2;
    //your code
}

Comparing with other approaches, this way is safe while not changing the frame or contentInsets of the tableview. Hope this may help.
