Question

I’m working witha simple tableview but I need to modify the font size for the text in the group header.

I’ve found this question on stackoverflow eferencing the tableview methods to override but I’m looking for an example of how I might modify the actual headers font size once I implement this method

Note: I’m able to modify the height of the header itself using interface builder but the font size appears to require some objective-c to modify this

Thank you in advance

Edit

here is what I have so far -it’s not throwing an exception but the header itself doesn’t show the text or font size I set on the label itself

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
    UIView* x = tableView.tableHeaderView;
    UILabel* y = [[UILabel alloc] initWithFrame:CGRectMake(5, 0, 310, 0)];
    y.font = [UIFont boldSystemFontOfSize:12.0];
    y.text = @"ha";
    [x addSubview:y];
    [y release];

    return x;
}

The header for a table may be set to any subclass of UIView. In particular, you can create a UILabel, set the text with your desired font size, then make the label the headerView.

Three potential problems with your edit:

1. Did you remember to implement tableView:heightForHeaderInSection:?

2. The height of your UILabel is currently 0.

3. When this method is called, tableView.tableHeaderView may not yet be defined.

My approach would be to declare UILabel *headerLabel and then add this to viewDidLoad:

headerLabel = [[UILabel alloc] initWithFrame:CGRectMake(5, 0, 310, 15)];
headerLabel.font = [UIFont boldSystemFontOfSize:12.0];
headerLabel.text = @"Testing";

Then have

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
    return 15.0;
}

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
    return headerLabel;
}
