我正在使用 Eureka Forms 在我的应用程序中创建一个注册函数。

我想弄清楚这个问题。

用户有一些字段需要提供给我们。在他删除所有信息并检查我们想要的所有按钮之前，我希望按钮提交为禁用或隐藏。当所需的行完成时，按钮应该可用/显示。

这是我用eureka做的类

class RegisterViewController: FormViewController {

    var xwra = 1
    override func viewDidLoad() {
        super.viewDidLoad()

        LabelRow.defaultCellUpdate = { cell, row in
            cell.contentView.backgroundColor = .red
            cell.textLabel?.textColor = .white
            cell.textLabel?.font = UIFont.boldSystemFont(ofSize: 13)
            cell.textLabel?.textAlignment = .right

        }

        TextRow.defaultCellUpdate = { cell, row in
            if !row.isValid {
                cell.titleLabel?.textColor = .red
            }
        }
        PhoneRow.defaultCellUpdate = { cell, row in
            if !row.isValid {
                cell.titleLabel?.textColor = .red
            }
        }
        PickerInlineRow<String>.defaultCellUpdate = { cell, row in
            if !row.isValid {
                cell.backgroundColor = .red
            }
        }

        PasswordRow.defaultCellUpdate = { cell, row in
            if !row.isValid {
                cell.titleLabel?.textColor = .red
            }
        }
        ButtonRow.defaultCellUpdate = { cell, row in
            cell.textLabel?.numberOfLines = 0
        }

有人能告诉我如何让它发挥作用吗？ 非常感谢!

更新 1.

最后一个按钮

<<< ButtonRow("register") {
                $0.title = "Εγγραφή"
                $0.cell.backgroundColor = .red
                $0.cell.tintColor = .white
                }
                .onCellSelection { cell, row in
                    row.section?.form?.validate()

        }

在选择单元格时，检查所有需要的数据，如果不正确，文本会变为红色。 所以问题又是一样的。如果验证为真，我如何运行发送到服务器功能？

最佳答案

我遇到了同样的问题，下面的代码获取错误计数，如果它是 0 则表单正常，如果有任何错误则继续执行下一个函数，它什么都不做。

<<< ButtonRow() { (row: ButtonRow) -> Void in
            row.title = "LOGIN"
            }
            .onCellSelection { [weak self] (cell, row) in
                print("validating errors: \(row.section?.form?.validate().count)")
                if row.section?.form?.validate().count == 0{
                    self?.loginAction(row)
                }
    }
