Question

请找到以下不适合我的代码。

 @IBInspectable var pasteOption: Bool = true {
        didSet {
            func canPerformAction(action: Selector, withSender sender: AnyObject) -> Bool {
                if action == "selectAll:" {
                    return pasteOption
                }
                if action == "select:" {
                    return pasteOption
                }
                if action == "cut:" {
                    return pasteOption
                }
                if action == "copy:" {
                    return pasteOption
                }
                if action == "paste:" {
                    return pasteOption
                }
                return super.canPerformAction(action, withSender: sender)
            }
        }
    }

我想使用UITextfield禁用剪切，复制和粘贴IBInspectable。

您需要像这样定义您的var：

@IBInspectable var pasteOption: Bool = true

然后覆盖UITextField的{{1}}函数，如下所示：

canPerformAction

通过这样做，您可以为函数中定义的特定操作返回override func canPerformAction(action: Selector, withSender sender: AnyObject?) -> Bool { if action == "selectAll:" { return pasteOption } if action == "select:" { return pasteOption } if action == "cut:" { return pasteOption } if action == "copy:" { return pasteOption } if action == "paste:" { return pasteOption } return super.canPerformAction(action, withSender: sender) }的值（pasteOption，selectAll，select，cut并且在这种情况下为copy）任何时候您的文本字段都会打开编辑菜单。
