done-button 单击表格视图标题时删除 UITextfield

Question

我在 TableViewCell 上有一个文本字段。当我单击“完成”按钮时，文本字段会删除。当我向下滚动并向上滚动时，文本字段再次可见。

addSubview(search)

    search.leftViewMode = UITextField.ViewMode.always

    search.placeholder = "Поиск лекарств и товаров"
    search.backgroundColor = .white
    search.layer.cornerRadius = 10
    search.dropShadow(color: .black, opacity: 0.5, offSet: CGSize(width: 5, height: 5), radius: 5, scale: false)

Answer 1

   func textFieldShouldReturn(textField: UITextField) -> Bool {

        self.searchTextFieldShouldReturn = true
        textField.resignFirstResponder()

        return true
    }
