如何在 Swift 3.0 的 UITextField 菜单中隐藏粘贴选项？

Question

我尝试了针对这个类似问题发布的每个答案，但它在 Swift 3 中不起作用。

  override func canPerformAction(action: Selector, withSender sender: AnyObject?) -> Bool {
   if action == #selector(paste(_:)) {
        return false
    }
   return super.canPerformAction(action, withSender: sender)
}

谢谢

如果有人在寻找 swift 4.2

 override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
        OperationQueue.main.addOperation {
            UIMenuController.shared.setMenuVisible(false, animated: false)
        }

        return super.canPerformAction(action, withSender: sender)
    }
