ios - Eureka 表单(Swift)中的 MultipleSelectorRow 如何将 FormValues 转换为字符串数组？

Question

谁能帮我从 Eureka 表单的 MultipleSelectorRow 中检索值？

我有一个像这样的多选行，其中列出了楼层。

  <<< MultipleSelectorRow <String> {
            $0.title = "  *Floor"
            $0.tag = "floor"
            $0.options = floorArray
            $0.validationOptions = .validatesOnChange
            $0.add(rule: RuleRequired())
            }.onPresent { from, to in
               to.navigationItem.rightBarButtonItem = UIBarButtonItem(barButtonSystemItem: .done, target: from, action: #selector(SRElementsForInspectionVC.multipleSelectorDone(_:)))
            }.cellUpdate({(cell , row) in
                if !row.isValid{
                    // CELL BORDER HAS TO BE RED
                 cell.textLabel?.textColor = .red

                } else {
                    // do something
                }
            })

然后当我尝试检索我调用的提交按钮上的值时，

let formvalues = self.form.values()
    if let floor = formvalues["floor"]{
        if floor != nil{
            print(floor)

            for f in floor as! [String: Any] {
                let fl = f as! String
                print(fl)
                // Print the floor
            }

        }
    }

但我无法获得正确的转换。请帮忙。

是的，你可以这样解决

if let _floors = formvalues["floor"] as? Set<String> {
      for _floor in _floors{
          print(_floor)
      }
}
