Adding to terente's answer:

- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
    if (section == 0) {
        CGRect screenRect = [[UIScreen mainScreen] applicationFrame];
        UIView* headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, screenRect.size.width, 44.0)];
        //headerView.contentMode = UIViewContentModeScaleToFill;

        // Add the label
        UILabel *headerLabel = [[UILabel alloc] initWithFrame:CGRectMake(10.0, -5.0, 300.0, 90.0)];
        headerLabel.backgroundColor = [UIColor clearColor];
        headerLabel.opaque = NO;
        headerLabel.text = @"Header";
        headerLabel.textColor = [UIColor blackColor];
        headerLabel.highlightedTextColor = [UIColor blackColor];

        //this is what you asked
        headerLabel.font = [UIFont boldSystemFontOfSize:17];

        headerLabel.shadowColor = [UIColor clearColor];
        headerLabel.shadowOffset = CGSizeMake(0.0, 1.0);
        headerLabel.numberOfLines = 0;
        headerLabel.textAlignment = UITextAlignmentCenter;
        [headerView addSubview: headerLabel];

        [headerLabel release];  

        // Return the headerView
        return headerView;
    }
    else return nil;
}

You can use [UIFont fontWithName:@"" size:24.0]; for other fonts
