Question 68476 in IOS Swift Question posted in
The official documentation can be found here.

Is there a way to remove all UIActions from a UIControl? – Ios swift

or is there a way to check whether a UIControl has any UIActions?

Sometimes I want to change a UIControl’s behavior.
When using target-action, I can do it like this

button.removeTarget(nil, action: nil), for: .touchUpInside)
button.addTarget(self, action: #selector(didTouchUpInside()), for: .for: .touchUpInside)

    Why not you are using view.isUserInteractionEnabled = false? It will remove all the interaction ability of a view

    You can do this using enumerateEventHandlers:

    button.enumerateEventHandlers { action, targetAction, event, stop in
    if let action = action {
        // This is a UIAction
        button.removeAction(action, for: event)
    }
    if let (target, selector) = targetAction {
        // This is target / action
        button.removeTarget(target, action: selector, for: event)
    }
    stop = true // Ends iterating early if you are done
}

    Taking what jrturton has said here, you can turn it into a small extension:

    extension UIButton {
    func removeAllActions() {
        enumerateEventHandlers { action, _, event, _ in
            if let action = action {
                removeAction(action, for: event)
            }
        }
    }
}

    And now you can just call removeAllActions() on your UIButton to have the same effect.
