Вам нужно использовать numberOfLine = 0, если вы просто работаете с Single UILabel. Else. Вам нужно использовать ограничения.
import UIKit
class TableViewController: UITableViewController {
override func viewDidLoad() {
super.viewDidLoad()
tableView.register(UITableViewCell.self, forCellReuseIdentifier: "reuseIdentifier")
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return 5
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "reuseIdentifier", for: indexPath)
cell.textLabel?.numberOfLines = 0
cell.textLabel?.text = "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum."
return cell
}
}
В случае, если вам нужно использовать пользовательский UILabel, как ваш случай.
class TableViewController: UITableViewController {
override func viewDidLoad() {
super.viewDidLoad()
tableView.register(CustomCell.self, forCellReuseIdentifier: "reuseIdentifier")
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return 5
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "reuseIdentifier", for: indexPath) as! CustomCell
cell.myLabel.text = "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum."
return cell
}
}
class CustomCel: UITableViewCell {
let myLabel: UILabel = {
let label = UILabel()
label.numberOfLines = 0
label.translatesAutoresizingMaskIntoConstraints = false
return label
}()
func setupViews(){

myLabel.topAnchor.constraint(equalTo: self.topAnchor).isActive = true
myLabel.leftAnchor.constraint(equalTo: self.leftAnchor).isActive = true
myLabel.rightAnchor.constraint(equalTo: self.rightAnchor).isActive = true
myLabel.bottomAnchor.constraint(equalTo: self.bottomAnchor).isActive = true
}
