import UIKit

	override var canBecomeFirstResponder: Bool {

	}
	
	func showMenu(sender: AnyObject?) {
		becomeFirstResponder()
		let menu = UIMenuController.shared
		if !menu.isMenuVisible {
			menu.setTargetRect(bounds, in: self)
			menu.setMenuVisible(true, animated: true)
		}
	}
	
	override func copy(_ sender: Any?) {
		let board = UIPasteboard.general
		board.string = text

	}
	
	override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {

	}
}

I get a compile erro

Please help

addGestureRecognizer(UILongPressGestureRecognizer(target: self, action #selector(showMenu)))

Cannot invoke initializer for type 'UILongPressGestureRecognizer' with an argument list of type '(target: calculatorLabel, (CALayer, String) -> CAAction?, Selector)
Argument of '#selector' refers to instance method 'showMenu(sender:)' that is not exposed to Obejective-C
Add '@objc' to expose this instance method to Objective-C
Expected ',' separator

Just click "Fix" button in the error dialog.

but how i can select on UILabel?

but how i can select on UILabel?

override func copy(_ sender: Any?) {
let board = UIPasteboard.general
board.string = text
let menu = UIMenuController.shared
menu.setMenuVisible(false, animated: true)
}

I think that "text" is supposed to be where your UILabel's text goes.

I can find this code example in a 1000 places, but all it does is copying the entire label. No selection possible, so kinda useless. Or am I missing something ?
