Set a custom table view footer with Swift - ios

Question

I am trying to set a custom footer to my table view. I created the footer on a nib file and created a controlled for it.
class LoginTableFooter: UITableViewHeaderFooterView
In viewDidLoad() I wrote this code
let footerNib = UINib(nibName: "LoginTableFooter", bundle: nil)
tableView.register(footerNib, forHeaderFooterViewReuseIdentifier: "LoginTableFooter")
Then I implemented viewForFooterInSection
func tableView(_ tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
let cell = self.tableView.dequeueReusableHeaderFooterView(withIdentifier: "LoginTableFooter")
let header = cell as! LoginTableFooter
return cell
}
viewForFooterInSection was never called. I also tried to implement viewForHeaderInSection but it was also not called. Do you have an idea what is wrong? I have only one section in my table view; is it possible/better to set the footer directly on viewDidLoad?

Answer 1

Implement - delegate & datasource for your tableview and set both - heightForFooterInSection & viewForFooterInSection
tableView.delegate = self
tableView.dataSource = self
// set view for footer
func tableView(_ tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
let footerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.frame.size.width, height: 40))
footerView.backgroundColor = UIColor.blue
return footerView
}
// set height for footer
func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
return 40
}

//firstly you need to call the delegate and datasource of table view. i.e:
tableView.delegate = self
tableView.dataSource = self
//you need to call this delegate
func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
return "your expected footer height"
}

Swift 3
Directly use > viewForFooterInSection
override func tableView(_ tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
let footerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.frame.size.width, height: 40))
footerView.backgroundColor = UIColor.red
return footerView
}

func tableView(_ tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
let footerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.frame.size.width, height: 40))
footerView.backgroundColor = UIColor.red
return footerView
}
