This post has many nice solutions: How disable Copy, Cut, Select, Select All in UITextView

My favourite is to override canPerformAction:withSender::

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender {     if (action == @selector(paste:))         return NO;     return [super canPerformAction:action withSender:sender]; }

Storyboard users may want to look at this solution, as long as you are ok with subclassing.

I don't think that there is an easy way to achieve this through extensions or protocols.

Swift 3.1

import UIKit  @IBDesignable class CustomTextField: UITextField {      @IBInspectable var isPasteEnabled: Bool = true      @IBInspectable var isSelectEnabled: Bool = true      @IBInspectable var isSelectAllEnabled: Bool = true      @IBInspectable var isCopyEnabled: Bool = true      @IBInspectable var isCutEnabled: Bool = true      @IBInspectable var isDeleteEnabled: Bool = true      override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {         switch action {         case #selector(UIResponderStandardEditActions.paste(_:)) where !isPasteEnabled,              #selector(UIResponderStandardEditActions.select(_:)) where !isSelectEnabled,              #selector(UIResponderStandardEditActions.selectAll(_:)) where !isSelectAllEnabled,              #selector(UIResponderStandardEditActions.copy(_:)) where !isCopyEnabled,              #selector(UIResponderStandardEditActions.cut(_:)) where !isCutEnabled,              #selector(UIResponderStandardEditActions.delete(_:)) where !isDeleteEnabled:             return false         default:             //return true : this is not correct             return super.canPerformAction(action, withSender: sender)         }     } }
