Height of tableHeaderView seems to be 0

问题:

I tried to override the second tableHeaderView. But it seems that the height of it in the method heightForHeaderInSection seems to be 0. Can't explain it, do I have to put it in a iVar because in the viewForHeaderInSection I can set the view without any problems.

 - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
if(section == 0)
    return @"Adding a new list";
else
    return @"Other lists";

}

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {

if(section == 0) {
    return tableView.tableHeaderView;
} else {
    UIView *view = [[[UIView alloc] initWithFrame:CGRectMake(10, 10, 100, 50)] autorelease];
    view.backgroundColor = [UIColor redColor];

    return view;
}

}

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
if(section == 0)
    return tableView.tableHeaderView.frame.size.height;
else
    return 30;
}

回答1:

I think you are confusing the table header and the header for each section, they are different. There is no "second tableHeaderView", a UITableView has one tableHeaderView and then depends on the viewForHeaderInSection and heightForHeaderInSection methods to place custom header views for each section, otherwise you just use titleForHeaderInSection to place text there.
