How to add bottom border to tableview section header

Question

I'm using the following function to determine the tableview section header in my app:

override func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?{
    var title: UILabel = UILabel()
     title.text = "something" 
     // Add a bottomBorder
     var border = UIView(frame: CGRectMake(0,0,self.view.bounds.width,1))
     border.backgroundColor = UIColor.redColor()
     title.addSubview(border)
}

and the following section to determine the tableview section header height:

override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat

How can I add a bottom border to the section?

Answer 1

You can create UIView which will act as a border and then add it:

var border = UIView(frame: CGRectMake(0,40,self.view.bounds.width,1))
border.backgroundColor = UIColor.redColor()
headerView.addSubview(border)

headerView is your custom view that you actually create

EDIT

 var headerView = UIView(frame: CGRectMake(0,0,self.view.bounds.width,40))
 var title = UILabel(frame: CGRectMake(0, 0, 200, 21))
 title.text = "something" 
 // Add a bottomBorder
 var border = UIView(frame: CGRectMake(0,39,self.view.bounds.width,1))
 border.backgroundColor = UIColor.redColor()
 headerView.addSubview(border)
 headerView.addSubview(title)
 return headerView

EDIT

CGRectMake is not available anymore from Swift 3.0. Use CGRect instead

Answer 2

Swift 3

This worked for me. In viewForHeaderInSection:

  let headerView = UIView()

    let borderTop = UIView(frame: CGRect(x:0, y:0, width: tableView.bounds.size.width, height: 1.0))
    borderTop.backgroundColor = UIColor.self.init(red: 5/255, green: 16/255, blue: 28/255, alpha: 1.0)
    headerView.addSubview(borderTop)

    let borderBottom = UIView(frame: CGRect(x:0, y:40, width: tableView.bounds.size.width, height: 1.0))
    borderBottom.backgroundColor = UIColor.self.init(red: 5/255, green: 16/255, blue: 28/255, alpha: 1.0)
    headerView.addSubview(borderBottom)

You can adjust top and bottom position depending on you header high. y=0 for top and x=40 for bottom border works for me. Hopes this helps. Good luck.

If you want to customize the rest of the header:

 let headerLabel = UILabel(frame: CGRect(x: 15, y: 9, width: tableView.bounds.size.width, height: tableView.bounds.size.height))

    headerLabel.font = UIFont(name: "Trebuchet MS", size: 19)

    headerLabel.textColor = UIColor.self.init(red: 254/255, green: 170/255, blue: 25/255, alpha: 1.0)

    headerLabel.text = self.tableView(self.tableView, titleForHeaderInSection: section)

    headerLabel.sizeToFit()

    headerView.addSubview(headerLabel)
