How do I add this menu in iOS to an app? Menu similar to textfield in iPhone?

I would like to know how to implement this "context menu" with action buttons like the one that appears on whatsapp and other apps when you click message.

Thank you very much.

That is UIMenuController.

Swift

    let contextMenu = UIMenuController.shared
    contextMenu.menuItems = [
    UIMenuItem(title: "test", action: #selector(testclicked)),
    UIMenuItem(title: "test 1", action: #selector(test1clicked)),
    UIMenuItem(title: "test2", action: #selector(test2clicked)),
    UIMenuItem(title: "test3", action: #selector(test3clicked))
    ]
    contextMenu.showMenu(from: self.view, rect: CGRect(x: 100, y: 190, width: 100, height: 20))

Objective C

- (void)showMenu
{
    UIMenuController *menu = [UIMenuController sharedMenuController];
    menu.menuItems = @[
       [[UIMenuItem alloc] initWithTitle:@"Title1" action:@selector(MyAction1)],
       [[UIMenuItem alloc] initWithTitle:@"Title2" action:@selector(MyAction2)],
       [[UIMenuItem alloc] initWithTitle:@"Title3" action:@selector(MyAction)]];
    [menu setTargetRect:self.bounds inView:self];
    [menu setMenuVisible:YES animated:YES];
}

UPDATE: please use UIEditMenuInteraction now as UIMenuController is deprecated
