PEEK AND POP FOR UITABLEVIEW
Peek and Pop is a feature that is accessible from iPhone 6s and above. It is an action when user long press any UI elements on the screen we able to show a preview or quick menu actions by highlighting the pressed UI Element.So from this feature user can sense the 3D touch.
The Core Spell:
- Create tableView in storyboard.
- Implement delegate and data source methods for tableView.
- This is the main step where we implement the Contextual menu delegates of tableView.
Below is the storyboard design:
Implementing Essential Delegate and DataSource of UITableView:
Here we are going to show Menu option(UIContextualMennu) for peek a pop view having light and dark option which made themes according to the action.
Below is the tableView essential Delegate and DataSource methods:
extension ViewController: UITableViewDelegate, UITableViewDataSource{
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 5
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: “Cell”, for: indexPath)
return cell
}
}
Below is the output image for tableView:
Below is the final step, here we are going to implement contextual menu delegate for tableViewCell
func tableView(_ tableView: UITableView, contextMenuConfigurationForRowAt indexPath: IndexPath, point: CGPoint) -> UIContextMenuConfiguration? {
let configuration = UIContextMenuConfiguration(identifier: nil, previewProvider: nil) { actions -> UIMenu? in
let action = UIAction(title: “Dark Mode”, image: nil, identifier: .none) { action in
self.view?.overrideUserInterfaceStyle = .dark
}
let action2 = UIAction(title: “Light Mode”, image: nil, identifier: .none) { action in
self.view?.overrideUserInterfaceStyle = .light
}
return UIMenu.init(title: “SELECT MODE”, children: [action, action2])
}
return configuration
}
Below is the output images for peek and pop tableView:
Note: The above UIContextMenuConfiguration delegate available after iOS 13.0. Please check before implement this.
