adding some margin below section header text of a UITableView

问题

I have styled the header text:

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as? TableViewCell

    cell!.titleLabel!.text = sections[indexPath.section].objects[indexPath.row].name
    cell!.datetimeLabel!.text = "on " + sections[indexPath.section].objects[indexPath.row].date

    return cell!
}

func tableView(tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
   return 100
}

func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
        return sections[section].heading // Open Events
}

And I would like to add some margin / padding below it before the section of the table cells start. I have added some margin / padding top with heightForHeaderInSection. Any way to add some top / bottom margin / padding?

回答1:

titleForHeaderInSection method will have the default section header frame. You can use viewForHeaderInSection method to customize it. Try this code :

  override func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    let headerFrame = tableView.frame

    let title = UILabel()
    title.frame =  CGRectMake(10, 10, headerFrame.size.width-20, 20) //width equals to parent view with 10 left and right margin
    title.font = title.font.fontWithSize(14)
    title.text = self.tableView(tableView, titleForHeaderInSection: section) //This will take title of section from 'titleForHeaderInSection' method or you can write directly
    title.textColor = UIColor.blueColor()

    let headerView:UIView = UIView(frame: CGRectMake(0, 0, headerFrame.size.width, headerFrame.size.height))
    headerView.addSubview(title)

    return headerView
}

Hope this will work for you.

use viewForHeaderInSection: and return a view with a label with the correct spacing below it instead of using the default header in titleForHeaderInSection

see this answer for an example
