In tvOS, adding context menus and previews can greatly enhance the user experience by providing additional information and options without navigating away from the current screen. Below is an explanation and example of how to implement context menus and previews using Swift in a tvOS application.
To create a context menu in tvOS, you typically use the UIContextMenuInteraction
class along with the UITargetedPreview
for previews. This allows users to press and hold an item to see available actions, along with a preview of what the action would do.
Here is a simple example:
import UIKit
class MyViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
let myView = UIView(frame: CGRect(x: 100, y: 100, width: 200, height: 200))
myView.backgroundColor = .blue
self.view.addSubview(myView)
let interaction = UIContextMenuInteraction(delegate: self)
myView.addInteraction(interaction)
}
}
extension MyViewController: UIContextMenuInteractionDelegate {
func contextMenuInteraction(_ interaction: UIContextMenuInteraction,
configurationForMenuAt location: CGPoint) -> UIContextMenuConfiguration? {
let configuration = UIContextMenuConfiguration(identifier: nil, previewProvider: { () -> UIViewController? in
let previewController = UIViewController()
previewController.view.backgroundColor = .white
return previewController
}, actionProvider: { _ in
let action = UIAction(title: "Action", image: nil) { _ in
print("Action selected")
}
return UIMenu(title: "Menu", children: [action])
})
return configuration
}
}
