I am new to swift . I am following the programmatic approach to create the view . I created two stack view . One is horizontal and other one is vertical. Into horizontal stack view I want to display the label property and Vertical stack view I want to display the Image. I want to display the image on left side and label properties on right side.

Here is the code I used ..

import UIKit

class PeopleCell: UITableViewCell {

    
    static let identifier = "PeopleCell"
    
    private lazy var mainStackView: UIStackView = {
        let stackView = UIStackView()
        stackView.translatesAutoresizingMaskIntoConstraints = false
        stackView.axis = .vertical
        stackView.distribution = .fill
        stackView.alignment = .leading
        return stackView
    }()
    
    private lazy var stackView: UIStackView = {
        let stackView = UIStackView()
        stackView.translatesAutoresizingMaskIntoConstraints = false
        stackView.axis = .horizontal
        stackView.distribution = .fill
        stackView.alignment = .center
        return stackView
    }()
    private lazy var lastnameTitleLabel: UILabel = {
        let label = UILabel()
        label.translatesAutoresizingMaskIntoConstraints = false
        label.numberOfLines = 0
        label.textAlignment = .center
        return label
    }()
    
    private lazy var firstnameTitleLabel: UILabel = {
        let label = UILabel()
        label.translatesAutoresizingMaskIntoConstraints = false
        label.numberOfLines = 0
        label.textAlignment = .center
        return label
    }()
    
    private lazy var peopleImageView: UIImageView = {
        let imageView = UIImageView()
        imageView.translatesAutoresizingMaskIntoConstraints = false
        imageView.contentMode = .scaleAspectFit
       // imageView.backgroundColor = .blue
        return imageView
    }()
    
    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
        
        setUpUI()
    }
   
    
   required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    
    func configureCell(firstName: String, lastName: String) {
        firstnameTitleLabel.text = "Firstname :\(firstName)"
        lastnameTitleLabel.text = "Lastname : \(lastName)"
        
        }
        
    
    func configureImageCell(row: Int, viewModel: ViewModel) {
        
        peopleImageView.image = nil
        
        viewModel
            .downloadImage(row: row) { [weak self] data in
                let image = UIImage(data: data)
                self?.peopleImageView.image = image
            }
    }
    
    private func setUpUI() {
        
        stackView.addArrangedSubview(lastnameTitleLabel)
        stackView.addArrangedSubview(firstnameTitleLabel)
        
        mainStackView.addArrangedSubview(peopleImageView)
        mainStackView.addArrangedSubview(stackView)
        
        contentView.addSubview(mainStackView)
        
        // constraints
        let safeArea = contentView.safeAreaLayoutGuide
        
        mainStackView.topAnchor.constraint(equalTo: safeArea.topAnchor).isActive = true
        mainStackView.bottomAnchor.constraint(equalTo: safeArea.bottomAnchor).isActive = true
        mainStackView.leadingAnchor.constraint(equalTo: safeArea.leadingAnchor, constant: 10).isActive = true
        mainStackView.trailingAnchor.constraint(equalTo: safeArea.trailingAnchor, constant: -10).isActive = true
        
        peopleImageView.heightAnchor.constraint(equalToConstant: 140).isActive = true
        peopleImageView.widthAnchor.constraint(equalToConstant: 140).isActive = true
        
        stackView.leadingAnchor.constraint(equalTo: mainStackView.leadingAnchor).isActive = true
        stackView.trailingAnchor.constraint(equalTo: mainStackView.trailingAnchor).isActive = true
        
        
    }
}

Here is the screenshot ..

Here is the expected result.

CodePudding user response：

The main problem is that you have your .axis properties reversed.

You want your mainStackView.axis to be .horizontal and your stackView.axis to be .vertical.

Also, these two lines are not needed (and cause problems):

// don't do this
//stackView.leadingAnchor.constraint(equalTo: mainStackView.leadingAnchor).isActive = true
//stackView.trailingAnchor.constraint(equalTo: mainStackView.trailingAnchor).isActive = true

As a side note, instead of:

let safeArea = contentView.safeAreaLayoutGuide

you may want to use:

let safeArea = contentView.layoutMarginsGuide

which gives you the default cell margins.

Edit

// this is the "main" stack view with
//   the image on the left
//   the labels on the right
// so it needs to be HORIZONTAL
private lazy var mainStackView: UIStackView = {
    let stackView = UIStackView()
    stackView.translatesAutoresizingMaskIntoConstraints = false

    //stackView.axis = .vertical
    stackView.axis = .horizontal

    stackView.distribution = .fill
    return stackView
}()

// this is the "labels" stack view with
//   two (or more) labels from top down
// so it needs to be VERTICAL
private lazy var stackView: UIStackView = {
    let stackView = UIStackView()
    stackView.translatesAutoresizingMaskIntoConstraints = false

    //stackView.axis = .horizontal
    stackView.axis = .vertical

    stackView.distribution = .fill
    return stackView
}()
