テーブルセルの自動レイアウトが希望どおりに配置されない問題

プログラムで実行してみてください。この例では、numberOfRowsInSectionを20を返すように設定し、UITableViewCellクラスにオブジェクトを設定します。

let containerViw: UIView = {
    let myView = UIView()
    myView.translatesAutoresizingMaskIntoConstraints = false
    myView.heightAnchor.constraint(equalToConstant: 100).isActive = true
    myView.widthAnchor.constraint(equalToConstant: 100).isActive = true
    return myView
}()

lazy var buttonPlay: UIButton = {
    let button = UIButton(type: .system)
    let image = UIImage(systemName: "play.circle")
    button.setBackgroundImage(image, for: .normal)
    button.addTarget(self, action: #selector(handlePlay), for: .touchUpInside)
    button.translatesAutoresizingMaskIntoConstraints = false
   
    return button
}()

let dummyLabel: UILabel = {
    let label = UILabel()
    label.text = "Dummy Label"
    label.font = .systemFont(ofSize: 16, weight: .regular)
    label.textColor = .black
    
    return label
}()

let finestraBackground: UIImageView = {
    
    let imageView = UIImageView()
    imageView.backgroundColor = .red
    imageView.image = UIImage(named: "yourImage")?.withRenderingMode(.alwaysOriginal)
    imageView.translatesAutoresizingMaskIntoConstraints  = false
    imageView.heightAnchor.constraint(equalToConstant: 100).isActive = true
    imageView.widthAnchor.constraint(equalToConstant: 100).isActive = true
    imageView.layer.cornerRadius = 50
    imageView.layer.masksToBounds = true
    
    return imageView
}()

UITableViewCell.CellStyleでstackViewを設定し、制約を追加します。

override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
    super.init(style: style, reuseIdentifier: reuseIdentifier)
    
    backgroundColor = .white
    
    containerViw.addSubview(buttonPlay)
    buttonPlay.heightAnchor.constraint(equalToConstant: 50).isActive = true
    buttonPlay.widthAnchor.constraint(equalToConstant: 50).isActive = true
    buttonPlay.centerYAnchor.constraint(equalTo: containerViw.centerYAnchor).isActive = true
    buttonPlay.centerXAnchor.constraint(equalTo: containerViw.centerXAnchor).isActive = true
    
    let stackView = UIStackView(arrangedSubviews: [finestraBackground, dummyLabel, containerViw])
    stackView.distribution = .fillProportionally
    stackView.spacing = 10
    stackView.translatesAutoresizingMaskIntoConstraints = false
    
    contentView.addSubview(stackView)
    stackView.topAnchor.constraint(equalTo: contentView.topAnchor, constant: 10).isActive = true
    stackView.leadingAnchor.constraint(equalTo: contentView.leadingAnchor, constant: 10).isActive = true
    stackView.trailingAnchor.constraint(equalTo: contentView.trailingAnchor, constant: -10).isActive = true
    stackView.bottomAnchor.constraint(equalTo: contentView.bottomAnchor, constant: -10).isActive = true
}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}

最後のステップでは、再生用の関数を設定します。

@objc fileprivate func handlePlay() {
    print("Play...")
}

そしてこれは結果です：

完全なコード：

class TableViewCellCustom: UITableViewCell {

let containerViw: UIView = {
    let myView = UIView()
    myView.translatesAutoresizingMaskIntoConstraints = false
    myView.heightAnchor.constraint(equalToConstant: 100).isActive = true
    myView.widthAnchor.constraint(equalToConstant: 100).isActive = true
    return myView
}()

lazy var buttonPlay: UIButton = {
    let button = UIButton(type: .system)
    let image = UIImage(systemName: "play.circle")
    button.setBackgroundImage(image, for: .normal)
    button.addTarget(self, action: #selector(handlePlay), for: .touchUpInside)
    button.translatesAutoresizingMaskIntoConstraints = false
   
    return button
}()

let dummyLabel: UILabel = {
    let label = UILabel()
    label.text = "Dummy Label"
    label.font = .systemFont(ofSize: 16, weight: .regular)
    label.textColor = .black
    
    return label
}()

let finestraBackground: UIImageView = {
    
    let imageView = UIImageView()
    imageView.backgroundColor = .red
    imageView.image = UIImage(named: "yourImage")?.withRenderingMode(.alwaysOriginal)
    imageView.translatesAutoresizingMaskIntoConstraints  = false
    imageView.heightAnchor.constraint(equalToConstant: 100).isActive = true
    imageView.widthAnchor.constraint(equalToConstant: 100).isActive = true
    imageView.layer.cornerRadius = 50
    imageView.layer.masksToBounds = true
    
    return imageView
}()

@objc fileprivate func handlePlay() {
    print("Play...")
}

override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
    super.init(style: style, reuseIdentifier: reuseIdentifier)
    
    backgroundColor = .white
    
    containerViw.addSubview(buttonPlay)
    buttonPlay.heightAnchor.constraint(equalToConstant: 50).isActive = true
    buttonPlay.widthAnchor.constraint(equalToConstant: 50).isActive = true
    buttonPlay.centerYAnchor.constraint(equalTo: containerViw.centerYAnchor).isActive = true
    buttonPlay.centerXAnchor.constraint(equalTo: containerViw.centerXAnchor).isActive = true
    
    let stackView = UIStackView(arrangedSubviews: [finestraBackground, dummyLabel, containerViw])
    stackView.distribution = .fillProportionally
    stackView.spacing = 10
    stackView.translatesAutoresizingMaskIntoConstraints = false
    
    contentView.addSubview(stackView)
    stackView.topAnchor.constraint(equalTo: contentView.topAnchor, constant: 10).isActive = true
    stackView.leadingAnchor.constraint(equalTo: contentView.leadingAnchor, constant: 10).isActive = true
    stackView.trailingAnchor.constraint(equalTo: contentView.trailingAnchor, constant: -10).isActive = true
    stackView.bottomAnchor.constraint(equalTo: contentView.bottomAnchor, constant: -10).isActive = true
}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}
}

更新、ストーリーボードなしで、上面図を使用してプログラムでtableViewの例を作成します

import UIKit

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

let cellId = "cellId"
let tableView = UITableView()

let containerView = UIView()
let dummyImageView = UIImageView()
let artistLabel = UILabel()

override func viewDidLoad() {
    super.viewDidLoad()
    
    artistLabel.text = "Artist Name\nArtist Song Name"
    artistLabel.font = .systemFont(ofSize: 16, weight: .semibold)
    artistLabel.numberOfLines = 0
    artistLabel.textColor = .white
    
    dummyImageView.image = UIImage(named: "yourImage")
    dummyImageView.contentMode = .scaleAspectFill
    dummyImageView.clipsToBounds = true
    dummyImageView.translatesAutoresizingMaskIntoConstraints = false
    dummyImageView.widthAnchor.constraint(equalToConstant: 150).isActive = true
    dummyImageView.heightAnchor.constraint(equalToConstant: 150).isActive = true
    dummyImageView.layer.cornerRadius = 75
    
    containerView.backgroundColor = .darkGray
    containerView.translatesAutoresizingMaskIntoConstraints = false
    
    
    tableView.delegate = self
    tableView.dataSource = self
    tableView.translatesAutoresizingMaskIntoConstraints = false
    
    tableView.register(TableViewCellCustom.self, forCellReuseIdentifier: cellId)
    
    view.addSubview(containerView)
    containerView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor).isActive = true
    containerView.leadingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leadingAnchor).isActive = true
    containerView.trailingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.trailingAnchor).isActive = true
    containerView.heightAnchor.constraint(equalToConstant: 200).isActive = true
    
    let stackView = UIStackView(arrangedSubviews: [dummyImageView, artistLabel])
    stackView.axis = .horizontal
    stackView.spacing = 10
    stackView.distribution = .fillProportionally
    stackView.translatesAutoresizingMaskIntoConstraints = false
    
    containerView.addSubview(stackView)
    stackView.heightAnchor.constraint(equalToConstant: 150).isActive = true
    stackView.trailingAnchor.constraint(equalTo: containerView.trailingAnchor, constant: -20).isActive = true
    stackView.leadingAnchor.constraint(equalTo: containerView.leadingAnchor, constant: 10).isActive = true
    stackView.centerYAnchor.constraint(equalTo: containerView.centerYAnchor).isActive = true
    
    view.addSubview(tableView)
    tableView.topAnchor.constraint(equalTo: containerView.bottomAnchor).isActive = true
    tableView.leadingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leadingAnchor).isActive = true
    tableView.trailingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.trailingAnchor).isActive = true
    tableView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true
}

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return 120
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return 20
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: cellId, for: indexPath) as! TableViewCellCustom
    
    return cell
}
}

シーンデリゲートで、次のようにナビゲーションコントローラーをアクティブにします。

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    guard let windowScene = (scene as? UIWindowScene) else { return }
    
    window = UIWindow(windowScene: windowScene)
    //        let controller = UINavigationController(rootViewController: ViewController())//if you want navigation controller uncomment that
    let controller = ViewController() // if you want navigation Controller COMMENT That
    window?.makeKeyAndVisible()
    window?.rootViewController = controller
}

または、didSelecrRowAtメソッドを使用できます。TableViewControllerに次の2行を追加するだけです。

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    print("Play...", indexPath.row)
}
