iOS 14的似乎可以从任何或/中呈现,但我如何从通用的中呈现它?
添加交互:
let interaction = UIContextMenuInteraction(delegate: self)
menuView.addInteraction(interaction)
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 :)
目前无法直接从UIView中显示菜单。
最好的解决方法是将UIButton作为子视图添加,并使用UIButton来显示菜单。这样可以避免长按操作。
button.menu = UIMenu(title: "", image: nil, identifier: nil, options: [], children: menuActions)
button.showsMenuAsPrimaryAction = true
view.addSubview(button)
view.sendSubviewToBack(button)
//add necessary constraints to position the button as you please
