UITableViewCell size does not change - ios

Question

I cannot understand why the cells do not resize according to the given .xib file
This is my table controller
import Foundation
import UIKit
class RecipeTableView: UIViewController {
let cellIdentifier = "RecipeTableViewCell"
#IBOutlet weak var recipeTableView: UITableView!
private let localDatabaseManager: LocalDatabaseManager = LocalDatabaseManager.shared
private var recipes = [Recipe]()
override func viewDidLoad() {
super.viewDidLoad()
recipeTableView.dataSource = self
recipeTableView.delegate = self
//recipeTableView.rowHeight = UITableView.automaticDimension
//recipeTableView.estimatedRowHeight = UITableView.automaticDimension
self.recipeTableView.register(UINib(nibName: cellIdentifier, bundle: nil), forCellReuseIdentifier: cellIdentifier)
localDatabaseManager.loadRecipes { [weak self] (recipes) in
guard let recipes = recipes else {
return
}
self?.recipes = recipes
DispatchQueue.main.async {
self?.recipeTableView.reloadData()
}
}
}
// override func viewWillAppear(_ animated: Bool) {
// recipeTableView.estimatedRowHeight = 256
// recipeTableView.rowHeight = UITableView.automaticDimension
// }
}
extension RecipeTableView: UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
recipes.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
guard let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as? RecipeTableViewCell else {
return UITableViewCell()
}
let recipe = recipes[indexPath.row]
cell.configure(with: recipe)
//cell.layer.cornerRadius = 32
//cell.layer.masksToBounds = true
return cell
}
}
extension RecipeTableView: UITableViewDelegate {
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
}
And my cell swift file
import Foundation
import UIKit
import Kingfisher
import Cosmos
class RecipeTableViewCell: UITableViewCell {
#IBOutlet weak var recipeNameLabel: UILabel!
#IBOutlet weak var recipeDescriptionLabel: UILabel!
#IBOutlet weak var recipeImageView: UIImageView!
#IBOutlet weak var recipeCosmosView: CosmosView!
override func prepareForReuse() {
super.prepareForReuse()
recipeNameLabel.text = nil
recipeDescriptionLabel.text = nil
recipeImageView.image = nil
}
func configure(with recipe: Recipe) {
recipeNameLabel?.text = recipe.name
recipeDescriptionLabel?.text = recipe.description
//let imageBytes = recipe.imageData
//let imageData = NSData(bytes: imageBytes, length: imageBytes.count)
//let image = UIImage(data: imageData as Data)
//recipeImageView?.image = image
let imageUrl = URL(string: recipe.imageData)
recipeImageView?.kf.setImage(with: imageUrl)
recipeCosmosView.settings.fillMode = .precise
recipeCosmosView.rating = recipe.rating
}
}
here is what my custom cell looks like
here is how these cells are shown in the app
I already found similar questions, but everywhere the same answer. Need to add the following lines. So I tried.
override func viewWillAppear(_ animated: Bool) {
recipeTableView.estimatedRowHeight = 256
recipeTableView.rowHeight = UITableView.automaticDimension
}
But it did not work

Answer 1

I think you need to call another tableView method for set the height for each cell according to his content
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
// add estimated height here ....
//...
return indexPath.row * 20
}
