How do I auto-display length in Table View? - swift

Question

I can't determine the length of Cell TableView automatically
in Swift ,UIKit
I tried all the ways
Either it gives me a fixed length or the values in the Cell tableview are not shown
These are Table View codes
extension DetilesVC : UITableViewDelegate , UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return arrQ.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! CellDetiles
let date = arrQ[indexPath.row]
cell.arrQR = date
return cell
}
func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableView.automaticDimension
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableView.automaticDimension
}
}
If I don't put this value here like this
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 900
}
Table View shouts like this
My Cell TableView
var arrQR : QRModel? {
didSet {
SetupQR()
}
}
func SetupQR () {
qusLabel.text = arrQR?.sub
detailLabel.text = arrQR?.detiles
}

Answer 1

In cellForRowAt put following code to show values in cells -
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! CellDetiles
let date = arrQ[indexPath.row]
cell.textLabel?.text = date
return cell
}
