UITextField to disallow all actions like copy, paste etc.

If we want to disable all the actions like Copy, Paste, Replace, Select, etc from UITextField then we can use following custom text field:

class CustomTextField: UITextField {var enableLongPressActions = falserequired init(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)!}override init(frame: CGRect) {
    super.init(frame: frame)}override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
    return enableLongPressActions} }

Using enableLongPressActions property, we can enable all actions any time later, if needed.
