swift中SkyFloatingLabelTextField中如何禁用复制粘贴功能？

Question

I am using the SkyFloatingLabelTextField class for UITextfield,How can I disable the Copy and paste functionality on this textfiled.

Answer 1

Use this technique for custom textField

   class SkyFloatingLabelTextField: UITextField {
        open override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
            if action == #selector(UIResponderStandardEditActions.paste(_:)) {
                return false
            }
            return super.canPerformAction(action, withSender: sender)
        }
    }

Answer 2

Create a custom class inherited from SkyFloatingLabelTextField class and then assign.

class FloatingTextField: SkyFloatingLabelTextField {
    open override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
        if action == #selector(UIResponderStandardEditActions.paste(_:)) ||
            action == #selector(UIResponderStandardEditActions.copy(_:)) {
            return false
        }
        return super.canPerformAction(action, withSender: sender)
    }
}

If you want for the whole project and all textfield add this extension.

extension SkyFloatingLabelTextField {
    open override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
        if action == #selector(UIResponderStandardEditActions.paste(_:)) ||
            action == #selector(UIResponderStandardEditActions.copy(_:)) {
            return false
        }
        return super.canPerformAction(action, withSender: sender)
    }
}
