我正在使用 Eureka Forms 在我的应用程序中创建注册功能。
我想弄清楚这个问题。
用户有一些需要给我们的字段。在他关闭所有信息并检查我们想要的所有按钮之前，我希望按钮提交被禁用或隐藏。当所需的行完成时，按钮应该可用/显示。
这是我用尤里卡制作的课程
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工作吗？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()
}
在单元格选择中，检查所有需要的数据，如果它们不正确，则文本变为红色。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？
