如何解决iOS 14 从 UIView 呈现 UIMenu
iOS 14 的 UIMenu
似乎可以从任何 UIBarButtonItem
或 UIButton
/ UIControl
呈现,但我将如何从通用 {{1 }}?
解决方法
添加交互:
let interaction = UIContextMenuInteraction(delegate: self)
menuView.addInteraction(interaction)
将 UIContextMenuInteractionDelegate 添加到您的控制器:
extension YourViewController: UIContextMenuInteractionDelegate {
func contextMenuInteraction(_ interaction: UIContextMenuInteraction,configurationForMenuAtLocation location: CGPoint) -> UIContextMenuConfiguration? {
return UIContextMenuConfiguration(identifier: nil,previewProvider: nil) { suggestedActions in
// Create an action for sharing
let share = UIAction(title: "Share",image: UIImage(systemName: "square.and.arrow.up")) { action in
// Show system share sheet
}
// Create an action for renaming
let rename = UIAction(title: "Rename",image: UIImage(systemName: "square.and.pencil")) { action in
// Perform renaming
}
// Here we specify the "destructive" attribute to show that it’s destructive in nature
let delete = UIAction(title: "Delete",image: UIImage(systemName: "trash"),attributes: .destructive) { action in
// Perform delete
}
// Create and return a UIMenu with all of the actions as children
return UIMenu(title: "",children: [share,rename,delete])
}
}
}
现在,长按视图并查看您的菜单:)
