swift - 如何快速禁用 SkyFloatingLabelTextField 中的复制粘贴功能？

Question

我正在为 UITextfield 使用 SkyFloatingLabelTextField 类，如何禁用此文本文件上的复制和粘贴功能。

Answer 1

将此技术用于自定义文本字段

   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

创建一个继承自 SkyFloatingLabelTextField 类的自定义类，然后赋值。

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)
    }
}

如果您想为整个项目和所有文本字段添加此扩展名。

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)
    }
}
