AutoResizing header & Cell in Programmatically UITableView - ios

Question

I have UIViewTable created programmatically
I customised the headers and cell look via Extension.
All I need is to make the large amount of texts displayed in header/cell to be viewed with:
lineBreakMode = NSLineBreakMode.byWordWrapping // enable multi line
numberOfLines = 0 // for Automatic size
I nearly used everything, but nothing is working.
I used:
self.tableView.estimatedRowHeight = 200.0
self.tableView.rowHeight = UITableView.automaticDimension
I put:
override func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
return 100
}
I also did:
override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableView.automaticDimension
}
Nothing seems to work
here is my Extension:
extension indexController {
override func numberOfSections(in tableView: UITableView) -> Int {
return sections.count
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
let subDatas = sections[section].sub_catigories // [1]
return subDatas?.count ?? 0
}
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let currentSection = sections[indexPath.section]
let currentSubdata = currentSection.sub_catigories?[indexPath.row]
//print(currentSubdata!.id)
let vc = indexControllerTwo()
vc.catNumber = currentSubdata!.id
vc.sectionTitle = currentSubdata?.name
navigationController?.pushViewController(vc, animated: true)
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cellid", for: indexPath)
// [2]
let currentSection = sections[indexPath.section]
let currentSubdata = currentSection.sub_catigories![indexPath.row]
// use listCell
guard let titleCell = cell as? listCell else {
return cell
}
titleCell.titleLabel.text = currentSubdata.name
titleCell.listCount.text = "\(currentSubdata.number_of_subcatigories ?? 0)"
// titleCell.titleLabel.numberOfLines = 3
// titleCell.titleLabel.lineBreakMode = NSLineBreakMode.byWordWrapping
// titleCell.titleLabel.baselineAdjustment = .alignCenters
// titleCell.titleLabel.adjustsFontSizeToFitWidth = true
// self.tableView.estimatedRowHeight = 200.0
// self.tableView.rowHeight = UITableView.automaticDimension
cell.layer.backgroundColor = UIColor.clear.cgColor
return cell
}
Please note that: listCell is just for customization and constraint
and here it is:
import UIKit
class listCell: UITableViewCell {
var safeArea: UILayoutGuide!
let imageCell = UIImageView()
let titleLabel = UILabel()
let subTitleLabel = UILabel()
let listCount = UILabel()
override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
setupView()
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func setupView(){
safeArea = layoutMarginsGuide
setupTitleLabel()
setupListCount()
}
func setupTitleLabel(){
addSubview(titleLabel)
titleLabel.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
titleLabel.leadingAnchor.constraint(equalTo: safeArea.leadingAnchor),
titleLabel.topAnchor.constraint(equalTo: topAnchor, constant: 7)
])
titleLabel.font = UIFont(name: "verdana-Bold", size: 16)
}
func setupListCount(){
addSubview(listCount)
listCount.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
listCount.leadingAnchor.constraint(equalTo: safeArea.trailingAnchor, constant: -30),
listCount.topAnchor.constraint(equalTo: titleLabel.bottomAnchor, constant: -11)
])
listCount.font = UIFont(name: "verdana", size: 10)
}
}
Please help me make the header and cell text field to be auto resizing.
thanks for your time.
