CopyableLabel

UILabel extension to enable copying

Usage

import CopyableLabel

let label = UILabel()
label.copyable = true

Or set copyable property to true in Interface Builder.

If another object (e.g. UIViewController) has a need to know which CopyableLabel has invoked the UIMenuController (i.e. presented the 'Copy' balloon, register the object for CopyableLabel.didShowCopyMenuNotification notification:

NotificationCenter.default.addObserver(self, selector: #selector(receivedCopyableLabelNotification(_:)), name: CopyableLabel.didShowCopyMenuNotification, object: nil)

The registering object will receive a Notification that contains a reference to the CopyableLabel that posted the notification.

@objc func receivedCopyableLabelNotification(_ notification: NSNotification) {
    if let label = notification.object as? UILabel {
        print(label.text!)
    }
}

UIMenuController does post a UIMenuController.didShowMenuNotification, however that notification does not provide any additional information (i.e. which UI elemement posted the notification, where the menu is, etc.).

Register for the UIMenuController willHide or didHide notifications, if you need to know when the menu is dismissed.
