How to Implement ImagePlaygroundViewController in swift?
ImagePlaygroundViewController
is not a standard or predefined class in iOS development. However, it sounds like a custom UIViewController
created for a specific purpose, possibly to display and manipulate images within an iOS application. Below is a breakdown of how such a view controller could be structured and implemented in Swift:Code :
import UIKit class ImagePlaygroundViewController: UIViewController { // MARK: - Properties var imageView: UIImageView! var selectedImage: UIImage? override func viewDidLoad() { super.viewDidLoad() setupUI() } // MARK: - Setup UI private func setupUI() { view.backgroundColor = .white // Image View imageView = UIImageView(frame: view.bounds) imageView.contentMode = .scaleAspectFit imageView.isUserInteractionEnabled = true if let image = selectedImage { imageView.image = image } view.addSubview(imageView) // Add gesture recognizers addGestures() // Add toolbar setupToolbar() } private func setupToolbar() { let toolbar = UIToolbar() toolbar.translatesAutoresizingMaskIntoConstraints = false view.addSubview(toolbar) NSLayoutConstraint.activate([ toolbar.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor), toolbar.leadingAnchor.constraint(equalTo: view.leadingAnchor), toolbar.trailingAnchor.constraint(equalTo: view.trailingAnchor), toolbar.heightAnchor.constraint(equalToConstant: 50) ]) let saveButton = UIBarButtonItem(barButtonSystemItem: .save, target: self, action: #selector(saveImage)) let shareButton = UIBarButtonItem(barButtonSystemItem: .action, target: self, action: #selector(shareImage)) toolbar.setItems([saveButton, UIBarButtonItem.flexibleSpace(), shareButton], animated: false) } // MARK: - Gesture Recognizers private func addGestures() { let pinchGesture = UIPinchGestureRecognizer(target: self, action: #selector(handlePinch(_:))) let panGesture = UIPanGestureRecognizer(target: self, action: #selector(handlePan(_:))) imageView.addGestureRecognizer(pinchGesture) imageView.addGestureRecognizer(panGesture) } @objc private func handlePinch(_ sender: UIPinchGestureRecognizer) { guard let view = sender.view else { return } view.transform = view.transform.scaledBy(x: sender.scale, y: sender.scale) sender.scale = 1.0 } @objc private func handlePan(_ sender: UIPanGestureRecognizer) { let translation = sender.translation(in: view) if let gestureView = sender.view { gestureView.center = CGPoint(x: gestureView.center.x + translation.x, y: gestureView.center.y + translation.y) } sender.setTranslation(.zero, in: view) } // MARK: - Toolbar Actions @objc private func saveImage() { guard let image = imageView.image else { return } UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil) let alert = UIAlertController(title: "Saved", message: "Image saved to Photos.", preferredStyle: .alert) alert.addAction(UIAlertAction(title: "OK", style: .default, handler: nil)) present(alert, animated: true, completion: nil) } @objc private func shareImage() { guard let image = imageView.image else { return } let activityVC = UIActivityViewController(activityItems: [image], applicationActivities: nil) present(activityVC, animated: true, completion: nil) } }
Use code :
let imagePlaygroundVC = ImagePlaygroundViewController() imagePlaygroundVC.selectedImage = UIImage(named: "exampleImage") navigationController?.pushViewController(imagePlaygroundVC, animated: true)
